Gimblet left the gun-room quietly; and after some more exploring discovered the way to the back premises.
In the pantry he found Blanston, whom he invited to follow him to the deserted billiard-room for a few minutes' conversation.
"You know," he told him, "Miss Byrne and your new young master want me to examine the evidence that Sir David Southern is the author of this terrible crime."
"I'm sure I wish, sir," said the man, "that you could prove he never did it. A very nice young gentleman, sir, Sir David has always been; it seems dreadful to think of him lifting his hand against his uncle. I'm sure it ought to be a warning to us all to keep our tempers, but of course it was very hard on Sir David to have his dog shot before his very eyes."
"No doubt," agreed Gimblet. "You weren't there when it happened, I suppose?"
"No, sir, but I heard about it from one of the keepers, and Sir David was very much put out about it, so he says; and I quite believe it, seeing how fond he was of the poor creature. Always had it to sleep in his room, he did, sir, though it was rather an offensive animal to the nose, to my way of thinking. But these young gentlemen what are always smoking cigarettes get to lose their sense of smell, I've often noticed that, sir. Oh, I understand he was very angry indeed, sir, but I should hardly have thought he would go so far as to take his uncle's life. Knowing him, as I have done, from a child, I may say I shouldn't hardly have thought it of him, sir."
"Life is full of surprises," said Gimblet, "and you never know for certain what anyone may not do; but, tell me, you were the first on the scene of the crime, weren't you?"
"Hardly that, sir. Miss Byrne was with his lordship at the time."
"Yes, yes, of course. But you saw him shortly after the shot was fired. Did you hear the report?"
"No, sir. The hall is quite away from the tower, and so is the housekeeper's room; and the walls are very thick. We were just finishing supper, which was very late that night on account of the gentlemen coming in late from stalking, and one thing and another. I'm rather surprised none of us heard it, sir."
"I daresay there was a good deal of noise going on," said Gimblet. "How many of you are there in the servants' quarters?"
"Counting the chauffeur and the hall boy," replied Blanston, "and including the visitors' maids, who are gone now, we were sixteen servants in the house that night. I am afraid there may have been rather a noise going on."
"Were you all there?" asked Gimblet. "Had no one left since the beginning of supper?"
"No one had gone out of the room or the hall since supper commenced," Blanston assured him. "We were all very glad of that afterwards, as it prevented any of us being suspected, sir. Though in point of fact I was saying only last night, when the second footman dropped the pudding just as he was bringing it into the room, that we could really have spared him better than what we could Sir David, sir; but of course it's natural for the household to be feeling a bit jumpy till after the funeral to-morrow. When that's over I shan't listen to no more excuses."
"Quite so," said Gimblet. "What was the first intimation you got that there was anything wrong?"
"About half-past ten the billiard-room bell rang very loud, in the passage outside the hall. Before it had stopped, and while I was calling to George, the first footman, to hurry up and answer it, there came another peal, and then another and another. I thought something must be wrong, so I ran out of the room and upstairs with the others. When we got to the billiard-room there was Miss Byrne fainting on a chair, and Mr. McConachan beside her, looking very upset like. 'There's been an accident or worse,' he says, 'to his lordship. Come on, Blanston, and let's see what it is. And you others look after Miss Byrne. Fetch her maid; fetch Lady Ruth.'
"And with that he makes for the library door, at a run, with me following him close, though I was a bit puffed with coming upstairs so fast. Just as we came to the library door, he turns and says to me, with his hand on the knob, 'From what Miss Byrne says, Blanston, I'm afraid it's murder.' And before I could more than gasp he had the door open, and we were in the room.
"There was his poor lordship lying forward on the table, his head on the blotting-book, and one arm hanging down beside him. Quite dead, he was, sir, and his blood all on the floor, poor gentleman. We left him as we found him, and went back.
"Mr. McConachan locked the door and put the key in his pocket. 'No one must go in there till the police come,' he says. 'But in the meantime we must get what men we can together, and see if the brute who did this isn't lurking about the grounds. It will be something if we can catch him, and avenge my poor uncle,' he said."
Gimblet considered for a moment.
"Are you sure you remember the position you found the body in?" he asked.
"Yes, sir," replied Blanston, in some surprise. "It was like I told you. His head on the blotting-book and one arm with it. He must have fallen straight forward on to the table."
"Thank you," said Gimblet. "One more question. I hear you witnessed a will for Lord Ashiel a day or two before he died?"
"Yes, sir--I and Mrs. Parsons, the housekeeper."
"How did you know it was the will?"
"We didn't exactly know it was, sir, but afterwards, when it came out his lordship had told Miss Byrne he had made one, we thought it must have been that."
"I see," said Gimblet. "Thank you. That is all I wanted to know."
He sent for the other servants and interrogated them one by one, but without adding anything fresh to what he had already learned.
He went thoughtfully away and sought out Mark in the smoking-room, where he found him surrounded by packets of papers, which lay in heaps upon the floor and tables.
"There's a frightful lot to look through," said the young man despondently, looking up from his self-imposed task. "I haven't found anything interesting yet. How did you get on? Do you think those footmarks can possibly be anyone's but David's?"
"The boot you gave me fits them too well to admit of doubt, I'm afraid," said Gimblet. And as the other made a half-gesture of despair, "You must give me more time," he said; "I may find some clue in the course of the next two or three days. By the by, is your cousin a short man?"
"No," said Mark, "he's about my height. Why do you ask?"
"Oh, I had an idea," said Gimblet evasively. "But if he's as tall as you, I had better begin again. I think I'll take a little stroll through the grounds," he added, "and then back to Lady Ruth Worsfold's house, and get a bath and a change."
"I shall see you at dinner-time," said Ashiel. "I am dining at the cottage. Au revoir till then."
Gimblet went out of the front door, and proceeded to make a tour of the Castle buildings.
Turning to his left round the front of the house, he passed the gun-room door, and went down a short path, which led to the level of the servants' quarters. These were built on the slope of the hill, so that what was a basement in the front of the house was level with the ground at the back.
Here more remains of the old fortress were to be seen. The various outbuildings that straggled down towards the loch had all once formed part of old block-houses or outlying towers; and, as the path descended farther down the hill, the detective found himself walking round the precipitous rock from which the single great tower still standing--the one in whose massive shell the room had been cut which was now the library--dominated the scene from every side.
It had been built at the very edge of the hill which here fell almost sheer to the level of the lake, and the old McConachans had no doubt chosen their site for its unscalable position. Indeed, the place must always have been impregnable from that side, the rock offering no foothold to a goat till within twenty feet of the base of the tower, where the surface was broken and uneven, and had, in places, been built up with solid masonry. In the crevices up there, seeds had germinated and grown to tall plants and bushes. Ivy hung about the face of the escarpment like a scarf, and in one place a good-sized tree, a beech, had established itself firmly upon a ledge and leant forward over the path below in a manner that turned the beholder giddy. Its great roots had not been able to grow to their full girth within the cracks and crannies of the rocks; some of them had pushed their way in through the gaps in the masonry, and the others curled and twisted in mid air, twining and interlacing in an outspread canopy.
Beyond the tower ran the battlemented wall of the enclosed garden, its foundations draped in the thrifty vegetation of the rocks.
At Gimblet's feet, on the other side of the path, brawled a burn, hurrying on its way to the loch, and he followed its course slowly down to the place where it mingled with the deep waters. A little beyond he saw the point of a fir-covered peninsula, and wandered on under the trees till he came to the end of it; there he sat down to think over what he had heard and seen that afternoon. The wild beauty of the place soothed and delighted him, and he felt lazily in his pocket for a chocolate.
Below him, grey lichen-grown rocks jutted into the loch in tumbled, broken masses, piled heedlessly one on the other, as if some troll of the mountain had begun in play to make a causeway for himself. The great stones, so old, so fiercely strong, stood knee-deep in the waters, over which they seemed to brood with so patient and indifferent a dignity that human life and affairs took on an aspect very small and inconsiderable. They were like monstrous philosophers, he thought, oblivious alike to time and to the cold waves that lapped their feet; their heads crowned here and there with pines as with scattered locks, the little tufts of heather and fern and grasses, that clung to them wherever root hold could be found, all the clothing they wore against the bitter blasts of the winds.
While he sat there a breeze got up and ruffled the loch; the ripples danced and sparkled like a cinematograph, and waves threw themselves among the rocks with loud gurglings and splashings. The air was suddenly full of the noise and hurry of the waters. He got up and went to the end of the peninsula. In spite of the dancing light upon the surface and the merry sounds of the ripples, the water, he could see, was deep and dark; a little way out a pale smooth stone rose a few feet above the level of it, its top draped in a velvet green shawl of moss. A fat sea-gull sat there; nor did it move when he appeared.
A little bay ran in between the rocks, its shore spread with grey sand, smooth and trackless. At least so Gimblet imagined it at first, as his eye roved casually over the beach. Then suddenly, with a smothered ejaculation, he leaped down from his perch of observation, and made his way to the margin of the water.
There, scored in the sand, was a deep furrow, reaching to within a foot of the waves, where it stopped as if it had been wiped out from a slate with a damp sponge. Gimblet had no doubt what it was. A boat had been beached here, and that lately. A glance at the stones surrounding the bay showed him that the water was falling, for in quiet little pools, within the outer breakwater of rocks, a damp line showed on the granite a full quarter of an inch above the water. By a rapid calculation of the time it would take for that watermark to dry, the detective was able to form some idea of the rate at which the loch was falling, and he thought he could judge the slope of the beach sufficiently well to calculate about how long it was since the track in the sand had reached to the brink of the waves.
It was a rough guess, but, if he were right, then a boat had landed in that bay some forty-two hours ago. But there were other traces, besides, the tracks of him who had brought the boat ashore. From where Gimblet stood, a double row of footprints, going and returning, showed plainly between the water and the stones to which the sand quickly gave place. They were the tracks left by large boots with singularly pointed toes, and with no nails on the soles. Emphatically not boots such as any of the men of those parts would be likely to wear.
Gimblet bent over the sand.
When he rose once more and stood erect upon the beach, he saw under the shadow of the pines the figure of a tall thin man with a lean face and straggling reddish moustache, who was watching him with an eye plainly suspicious. He was dressed in knickerbockers and coat of rough tweed of a large checked pattern, and carried a spy-glass slung over his back. The detective went to him at once.
"Are you employed on the Inverashiel estate?" he asked civilly.
"I'm Duncan McGregor, his lordship's head keeper," was the reply, given in the cold tones of one accosted by an intruder.
Gimblet hastened to introduce himself and to explain his presence, and McGregor condescended to thaw.
"I should be very much obliged," said Gimblet, "if you would take a look at the sands where you saw me standing. I'd like to know your opinion on some marks that are there."
The keeper strode down to the beach.
"A boat will have been here," he pronounced after a rapid scrutiny.
"Lately?" asked Gimblet.
He saw the man's eyes go, as his own had done, to the watermarks on the rocks.
"No sae vary long ago," he said, "I'm thinkin' it will hae been the nicht before lairst that she came here."
"Ah," said Gimblet, "I'm glad you agree with me. That's what I thought myself. Do boats often come ashore on this beach?"
McGregor considered.
"It's the first time I ever h'ard of onybody doin' the like," he said at last. "The landin' stage is awa' at the ether side o' the p'int; it's aye there they land. There's nae a man in a' this glen would come in here, unless it whar for some special reason. It's no' a vary grand place tae bring a boat in. The rocks are narrow at the mouth."
"Do strangers often come to these parts?"
"There are no strangers come to Inverashiel," said the keeper. "The high road runs at the ether side o' the loch through Crianan, and the tramps and motors go over it, but never hae I known one o' that kind on our shore."
Gimblet observed with some amusement that the man spoke of motors and tramps as of varieties of the same breed; but all he said was:
"Could you make inquiries as to whether anyone on the estate happens to have brought a boat in here during the last week? I should be glad if you could do so without mentioning my name, or letting anyone think it is important."
He felt he could trust the discretion of this taciturn Highlander.
"I'll that, sir," was the reply.
And Gimblet could see, in spite of the man's unchanging countenance, that he was pleased at this mark of confidence in him.
"Could you take me to the head gardener's house?" he asked, abruptly changing the subject. "I should rather like a talk with him."
McGregor conducted him down the road to the lodge.
"It's in here whar Angus Malcolm lives," he remarked laconically. "Good evening, sir."
He turned and strode away over the hillside, and Gimblet knocked at the door. It was opened by the gardener, and he had a glimpse through the open doorway of a family at tea.
"I'm sorry I disturbed you," he said. "I will look in again another day. Lord Ashiel referred me to you for the name of a rose I asked about, but it will do to-morrow."
The gardener assured him that his tea could wait, but Gimblet would not detain him.
"I shall no doubt see you up in the garden to-morrow," he said. "The roses in that long bed outside the library are very fine, and I am interested in their culture. I wonder they do so well in this peaty soil."
"Na fie, man, they get on splendid here," said Malcolm. He liked nothing better than to talk about his flowers, but, being a Highlander, resented any suggestion that his native earth was not the best possible for no matter what purpose. "We just gie them a good dressin' doon wie manure ilka year."
"Do you use any patent fertilizer?" Gimblet asked.
"Oh, just a clean oot wie a grain o' basic slag noo and than," said the gardener. "And I just gie them some lime ilka time I think the ground is needin' it."
"Well, the result is very good," said the detective. "By the way, have you been working on that bed lately? I picked this up among the violas. Did you happen to drop it?"
He took from his pocket a small paper notebook, and held it out interrogatively.
"Na, I hinna dropped it," answered the gardener. "It micht have been some one fay the castel. I hinna been near that rose-bed for fower or five days. And it couldna hae been lying there afore the rain."
Indeed, the little book showed no trace of damp on its green cover.
"I asked in the castle, but no one claimed it," said Gimblet. "Perhaps it belongs to one of your men?"
"There's been naebody been workin' there this week. So it disna belong tae neen o' the gair'ners, if it's there ye fund't," repeated Malcolm. "There's been nae work deen on that bed for the last fortnicht or mair. I was thinkin' o' sendin' a loon ower't wie a hoe in a day or twa. Ye see, wie the murrder it's been impossible tae get ony work done; apairt fay that we've been busy wie the fruit and ether things."
"I didn't notice any weeds," said Gimblet. "But I won't keep you any longer, now. Perhaps to-morrow afternoon I may see you in the garden, and if so I shall get you to tell me the name of that rose."
