"No, sir!" said Drillford, stoutly. "No luck at all--just a bit of good common-sense thinking on the part of a shrewd woman. But you'll want to know what we did. I was so absolutely certain of the truth of Miss Penkridge's theory that I immediately made preparations for a descent on Cortelyon's house. I got a number of our best men--detectives, of course--and we went round to Markendale Square, back and front. Inquiry showed that Cortelyon was out, but we'd scarcely got that fact ascertained when he drove up in a taxicab with Cave himself. They hurriedly entered the house--I myself was watching from a good point of vantage, and I saw that both men were, to say the least, anxious and excited. Then I began to make final preparations. But before I'd finished telling my men exactly what to do, another party drove up--your companion, Miss Wickham, Mrs. Killenhall. She too entered. Then I moved--quick. Some of us went to the front--I with the others went in by the back. We made straight for Cortelyon's surgery, and we were on him and the other two before they'd time to move, literally. The two men certainly tried to draw revolvers, but we were too many for 'em, and as they'd tried that game, I had 'em handcuffed there and then. It was all an affair of a moment--and of course, they saw it was all up. Now, equally of course, Mr. Viner, in all these cases, in my experience, the subordinates immediately try to save their own skins by denouncing the principal, and it was so in this instance. Mrs. Killenhall and Cave at once denounced Cortelyon as the mainspring, and the woman, who's a regular coward, got me aside and offered to turn King's evidence, and whispered that Cortelyon actually killed Ashton himself, unaided, as he let him out of his back door into Lonsdale Passage!" "So--that's settled!" exclaimed Viner. "Yes, I think so," agreed Drillford. "Well, we brought 'em all here, and charged 'em, and examined 'em. Nothing much on Cave, who, of course, is precisely what Hyde said he was--a man named Nugent Starr, an old actor--if he was as good a performer on the stage as he is in private life, he ought to have done well. But on Mrs. Killenhall we found ten thousand pounds in Bank of England notes, and one or two letters from Cortelyon, which she was a fool for keeping, for they clearly prove that she was an accessory. And on Cortelyon we'd a big find! That diamond that Ashton used to carry about, the other ring that Ashton was wearing when he was murdered, and--perhaps most important of all--certain papers which he'd no doubt taken from Ashton's body." "What are they?" demanded Viner. Drillford glanced at Miss Wickham.
