You may judge then of my surprise when there walked into my study at nine o'clock in the morning, and not over Mrs. Jardine's dead body, Billy Mackwith.

"Don't scold the old lady," he began without preface. "I suppose she hadn't any barbed wire except that on her chin—it is rather like one of the gooseberries we used to make on the old wiring-course. I had to see you."

"Had breakfast? Have a cup of coffee?" I asked him.

"Nothing, thanks. Well, I think I saved friend Philip a certain amount of trouble yesterday," he said, putting down his hat, stick and gloves. I don't think Mackwith buys a glossy new silk topper every time he goes out, but I do honestly believe he buys a new pair of lemon-colored gloves.

"Oh? How was that?"

"At the inquest on that fellow," he replied. "And by the way, I saw the Roundabout too. I suppose it has its humorous side, but it's very annoying too. I should go for 'em for libel. A house can be libeled, you know. Anyway, it's a good job he's out of town."

I was on the point of saying, "A good job he's what?" when I checked myself. If you remember, I had last seen William Mackwith, K.C., when I had left him at Sloane Square Station an hour or two after that confounded aeroplane accident. He and Hubbard had gone off to keep their respective appointments, while I myself had followed our check-coated friend Westbury into a public-house. Whether either Esdaile or Hubbard had seen him since I didn't know. I now gathered that Billy at any rate hadn't seen Esdaile.

"Yes?" I said. "What trouble have you been saving him?"

"Well, I told you—I saved him the bother of stopping for the inquest."

I had of course known that there must be an inquest, but I suppose I had been busy and had forgotten it again. This began to be interesting.
