“That will do, Billy,” said he. “You were in danger of your life then, my boy, and I can’t do without you just yet. Well, Watson, it is good to see you in your old quarters once again. You come at a critical moment.”

“So I gather.”

“You can go, Billy. That boy is a problem, Watson. How far am I justified in allowing him to be in danger?”

“Danger of what, Holmes?”

“Of sudden death. I’m expecting something this evening.”

“Expecting what?”

“To be murdered, Watson.”

“No, no, you are joking, Holmes!”

“Even my limited sense of humour could evolve a better joke than that. But we may be comfortable in the meantime, may we not? Is alcohol permitted? The gasogene and cigars are in the old place. Let me see you once more in the customary armchair. You have not, I hope, learned to despise my pipe and my lamentable tobacco? It has to take the place of food these days.”

“But why not eat?”

“Because the faculties become refined when you starve them. Why, surely, as a doctor, my dear Watson, you must admit that what your digestion gains in the way of blood supply is so much lost to the brain. I am a brain, Watson. The rest of me is a mere appendix. Therefore, it is the brain I must consider.”

“But this danger, Holmes?”

“Ah, yes, in case it should come off, it would perhaps be as well that you should burden your memory with the name and address of the murderer. You can give it to Scotland Yard, with my love and a parting blessing. Sylvius is the name – Count Negretto Sylvius. Write it down, man, write it down! 136 Moorside Gardens, N. W. Got it?”

Watson’s honest face was twitching with anxiety. He knew only too well the immense risks taken by Holmes and was well aware that what he said was more likely to be under-statement than exaggeration. Watson was always the man of action, and he rose to the occasion.

“Count me in, Holmes. I have nothing to do for a day or two.”

“Your morals don’t improve, Watson. You have added fibbing to your other vices. You bear every sign of the busy medical man, with calls on him every hour.”

“Not such important ones. But can’t you have this fellow arrested?”

“Yes, Watson, I could. That’s what worries him so.”

“But why don’t you?”

“Because I don’t know where the diamond is.”

“Ah! Billy told me – the missing Crown jewel!”

“Yes, the great yellow Mazarin stone. I’ve cast my net and I have my fish. But I have not got the stone. What is the use of taking them? We can make the world a better place by laying them by the heels. But that is not what I am out for. It’s the stone I want.”

“And is this Count Sylvius one of your fish?”

“Yes, and he’s a shark. He bites. The other is Sam Merton, the boxer. Not a bad fellow, Sam, but the Count has used him. Sam’s not a shark. He is a great big silly bull-headed gudgeon. But he is flopping about in my net all the same.”

“Where is this Count Sylvius?”

“I’ve been at his very elbow all the morning. You’ve seen me as an old lady, Watson. I was never more convincing. He actually picked up my parasol for me once. ‘By your leave, madame,’ said he – half-Italian, you know, and with the Southern graces of manner when in the mood, but a devil incarnate in the other mood. Life is full of whimsical happenings, Watson.”

“It might have been tragedy.”

“Well, perhaps it might. I followed him to old Straubenzee’s workshop in the Minories. Straubenzee made the air-gun – a very pretty bit of work, as I understand, and I rather fancy it is in the opposite window at the present moment. Have you seen the dummy? Of course, Billy showed it to you. Well, it may get a bullet through its beautiful head at any moment. Ah, Billy, what is it?”

The boy had reappeared in the room with a card upon a tray. Holmes glanced at it with raised eyebrows and an amused smile.

“The man himself. I had hardly expected this. Grasp the nettle, Watson! A man of nerve. Possibly you have heard of his reputation as a shooter of big game. It would indeed be a triumphant ending to his excellent sporting record if he added me to his bag. This is a proof that he feels my toe very close behind his heel.”

“Send for the police.”

“I probably shall. But not just yet. Would you glance carefully out of the window, Watson, and see if anyone is hanging about in the street?”

Watson looked warily round the edge of the curtain.

“Yes, there is one rough fellow near the door.”

“That will be Sam Merton – the faithful but rather fatuous Sam. Where is this gentleman, Billy?”

“In the waiting-room, sir.”

“Show him up when I ring.”

“Yes, sir.”

“If I am not in the room, show him in all the same.”

“Yes, sir.”

Watson waited until the door was closed, and then he turned earnestly to his companion.

“Look here, Holmes, this is simply impossible. This is a desperate man, who sticks at nothing. He may have come to murder you.”

“I should not be surprised.”

“I insist upon staying with you.”

“You would be horribly in the way.”

“In his way?”

“No, my dear fellow – in my way.”

“Well, I can’t possibly leave you.”

“Yes, you can, Watson. And you will, for you have never failed to play the game. I am sure you will play it to the end. This man has come for his own purpose, but he may stay for mine.” Holmes took out his notebook and scribbled a few lines. “Take a cab to Scotland Yard and give this to Youghal of the C. I. D. Come back with the police. The fellow’s arrest will follow.”

“I’ll do that with joy.”

“Before you return I may have just time enough to find out where the stone is.” He touched the bell. “I think we will go out through the bedroom. This second exit is exceedingly useful. I rather want to see my shark without his seeing me, and I have, as you will remember, my own way of doing it.”
