“It’s kind of you to give me a loophole of escape,” said Drummond pleasantly. “What are the eventualities to which you allude?”
“The non-return to me of a little bag containing diamonds,” remarked the hunchback quietly. “They were in the desk which was wrecked by the bomb.”
“Dear, dear,” said Hugh. “Am I supposed to have them in my possession?”
“I can only hope most sincerely for your sake that you have,” returned the other. “Otherwise I’m afraid that letter will go to the police.”
For a while Drummond smoked in silence: then, with a lazy smile on his face, he sat down in an armchair facing the hunchback.
“Most interesting,” he drawled. “Most interesting and entertaining. I’m not very quick, Mr.—, I’ve forgotten under what name you inflict yourself on a long-suffering world, but I shall call you Snooks—I’m not, as I say, very quick, Snooks, but as far as my brain can grapple with the problem it stands thus. If I give you back a packet of diamonds which I may, or may not, possess, you will refrain from informing the police that I am the leader of the Black Gang. If, on the contrary, I do not give them back to you, you will send them that interesting piece of information by means of an anonymous letter.” The smile grew even lazier. “Well, you damned little excrescence, I call your bluff. Get on with it.”
With a snarl of rage the hunchback snatched up his hat and rose to his feet.
“You call it bluff, do you?”—and his voice was shaking with fury. “Very good, you fool—I accept. And you’ll be sorry when you see my cards.”
“Sit down, Snooks: I haven’t finished with you yet.” There was still the same maddening smile on Drummond’s face, which disappeared suddenly as the hunchback moved towards the door. In two strides Hugh had him by the collar, and with a force that made his teeth rattle Mr. Atkinson found himself back in his chair.
“I said sit down, Snooks,” said Drummond pleasantly. “Don’t let me have to speak to you again, or I might hurt you. There are one or two things I have to say to you before depriving myself of the pleasure of your company. By the post following the one which carries your interesting disclosure will go another letter addressed to Sir Bryan Johnstone himself. I shall be in the office when he opens it—and we shall both be roaring with laughter over the extraordinary delusion that I—quite the biggest fool of his acquaintance—could possibly be the leader of the Black Gang. And, as if to prove the utter absurdity of the suggestion, this second letter will be from the leader of the Black Gang himself. In it he will state that he was present at 5, Green Street, Hoxton, last night, in an endeavour to obtain possession of the anarchist and Bolshevist literature stored there. That he took with him a professional burglar to assist him in opening the safe and other things which might be there, and that while engaged in this eminently virtuous proceeding he found that he was trapped in the room by some mechanical device. And then, Snooks, will come a very interesting disclosure. He will state how suddenly he saw through a crack in the door a pair of eyes looking at him. And their colour—see, what is the colour of your eyes, Snooks?—grey-blue, very noticeable. Much the same as old Longmoor’s—though his are a little bluer. And then the owner of the eyes, Snooks, was so inconsiderate as to throw a bomb in the room; a bomb which killed one of the men, and wrecked the desk. So that the owner of the eyes, Snooks, grey-blue eyes just like yours, is a murderer—a common murderer. And we hang men in England for murder.” He paused and stared at the hunchback. “This is a jolly game, isn’t it?”
“And you really imagine,” said the hunchback contemptuously, “that even your police would believe such a story that a man would wreck his own office, when on your own showing he had the men trapped inside it.”
“Probably not,” said Drummond affably. “Any more than that they would believe that I was the leader of the Black Gang. So since they’re such a wretched crowd of unbelievers I don’t think it’s much good playing that game, Snooks. Waste of time, isn’t it? So I vote we play another one, all on our own—a little game of make-believe—like we used to play in the nursery.”
“I haven’t an idea what you’re talking about, Captain Drummond,” said the hunchback, shifting uneasily in his chair. For all trace of affability had vanished from the face of the man opposite him, to be replaced by an expression which made Mr. Atkinson pass his tongue once or twice over lips that had suddenly gone dry.
“Haven’t you, you rat?” said Drummond quietly. “Then I’ll tell you. Just for the next five minutes we’re going to pretend that these two astonishing statements which the police—stupid fellows—won’t believe are true. We’re going to pretend—only pretend, mind you, Snooks—that I am the leader of the Black Gang; and we’re going to pretend that you are the man who flung the bomb last night. Just for five minutes only, then we go back to reality and unbelieving policemen.”
And if during the following five minutes strange sounds were heard by Denny in the room below, he was far too accustomed to the sounds of breaking furniture to worry. It wasn’t until the hunchback pulled a knife that Drummond warmed to his work, but from that moment he lost his temper. And because the hunchback was a hunchback—though endowed withal by Nature with singular strength—it jarred on Drummond to fight him as if
