“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.”
