The veins stood out on the Count’s forehead. His dark, hairy hands were clenched in a convulsion of restrained emotion. He tried to speak, but the words would not shape themselves.

“That’s the hand I play from,” said Holmes. “I put it all upon the table. But one card is missing. It’s the king of diamonds. I don’t know where the stone is.”

“You never shall know.”

“No? Now, be reasonable, Count. Consider the situation. You are going to be locked up for twenty years. So is Sam Merton. What good are you going to get out of your diamond? None in the world. But if you hand it over - well, I’ll compound a felony. We don’t want you or Sam. We want the stone. Give that up, and so far as I am concerned you can go free so long as you behave yourself in the future. If you make another slip - well, it will be the last. But this time my commission is to get the stone, not you.”

“But if I refuse?”

“Why, then - alas! - it must be you and not the stone.”

Billy had appeared in answer to a ring.

“I think, Count, that it would be as well to have your friend Sam at this conference. After all, his interests should be represented. Billy, you will see a large and ugly gentleman outside the front door. Ask him to come up.”

“If he won’t come, sir?”

“No violence, Billy. Don’t be rough with him. If you tell him that Count Sylvius wants him he will certainly come.”

“What are you going to do now?” asked the Count as Billy disappeared.

“My friend Watson was with me just now. I told him that I had a shark and a gudgeon in my net; now I am drawing the net and up they come together.”

The Count had risen from his chair, and his hand was behind his back. Holmes held something half protruding from the pocket of his dressing-gown.

“You won’t die in your bed, Holmes.”

“I have often had the same idea. Does it matter very much? After all, Count, your own exit is more likely to be perpendicular than horizontal. But these anticipations of the future are morbid. Why not give ourselves up to the unrestrained enjoyment of the present?”

A sudden wild-beast light sprang up in the dark, menacing eyes of the master criminal. Holmes’s figure seemed to grow taller as he grew tense and ready.

“It is no use your fingering your revolver, my friend,” he said in a quiet voice. “You know perfectly well that you dare not use it, even if I gave you time to draw it. Nasty, noisy things, revolvers, Count. Better stick to air-guns. Ah! I think I hear the fairy footstep of your estimable partner. Good day, Mr. Merton. Rather dull in the street, is it not?”

The prize-fighter, a heavily built young man with a stupid, obstinate, slab-sided face, stood awkwardly at the door, looking about him with a puzzled expression. Holmes’s debonair manner was a new experience, and though he vaguely felt that it was hostile, he did not know how to counter it. He turned to his more astute comrade for help.

“What’s the game now, Count? What’s this fellow want? What’s up?” His voice was deep and raucous.

The Count shrugged his shoulders, and it was Holmes who answered.

“If I may put it in a nutshell, Mr. Merton, I should say it was all up.”

The boxer still addressed his remarks to his associate.

“Is this cove trying to be funny, or what? I’m not in the funny mood myself.”
