If you please, sir, as a young visitor to the metropolis, and well acquainted with history, I want to ask you--
Who is the Constable of the Tower?
Is he dressed like other constables?
Can he run anyone in, and make them move on if found loitering on his beat?
Is his beat all round the Tower?
Is he a special? one of the force de tour, empowered to use a tour de force? (You see I am well up in French.)
I saw a very amiable-looking policeman cracking nuts in the vicinity of the Tower. Do you think this was the constable in question?
