“I have been working in that get-up all day,” said he, lighting his cigar. “You see, a good many of the criminal classes begin to know me—especially since our friend here took to publishing some of my cases: so I can only go on the war-path under some simple disguise like this. You got my wire?”

“Yes; that was what brought me here.”

“How has your case prospered?”

“It has all come to nothing. I have had to release two of my prisoners, and there is no evidence against the other two.”

“Never mind. We shall give you two others in the place of them. But you must put yourself under my orders. You are welcome to all the official credit, but you must act on the lines that I point out. Is that agreed?”

“Entirely, if you will help me to the men.”

“Well, then, in the first place I shall want a fast police-boat—a steam launch— to be at the Westminster Stairs at seven o’clock.”

“That is easily managed. There is always one about there, but I can step across the road and telephone to make sure.”

“Then I shall want two staunch men in case of resistance.”

“There will be two or three in the boat. What else?”

“When we secure the men we shall get the treasure. I think that it would be a pleasure to my friend here to take the box round to the young lady to whom half of it rightfully belongs. Let her be the first to open it. Eh, Watson?”

“It would be a great pleasure to me.”

“Rather an irregular proceeding,” said Jones, shaking his head. “However, the whole thing is irregular, and I suppose we must wink at it. The treasure must afterwards be handed over to the authorities until after the official investigation.”

“Certainly. That is easily managed. One other point. I should much like to have a few details about this matter from the lips of Jonathan Small himself. You know I like to work the details of my cases out. There is no objection to my having an unofficial interview with him, either here in my rooms or elsewhere, as long as he is efficiently guarded?”

“Well, you are master of the situation. I have had no proof yet of the existence of this Jonathan Small. However, if you can catch him, I don’t see how I can refuse you an interview with him.”

“That is understood, then?”

“Perfectly. Is there anything else?”

“Only that I insist upon your dining with us. It will be ready in half an hour. I have oysters and a brace of grouse, with something a little choice in white wines. —Watson, you have never yet recognized my merits as a housekeeper.”
