“Which means that Mrs. Fleetwood is Mrs. Fleetwood, and that she's legally married now. She won't be sorry to hear it. That's why I sent Mme. Laurent-Desrousseaux up there now. First-hand evidence is better than documents; and, of course, the documents will be forthcoming if they're required in future. Evidently those three scoundrels didn't know this latest twist in the affair, or they wouldn't have tried the trick they did last night. They'd have done worse, probably, when they got hold of her. If she'd been dead and out of the way, there would have been no one except old Miss Fordingbridge to contest that impostor's claim—and she was so besotted with him that she'd never have dreamed of doing so.”

He paused for a moment or two, as though considering the case; but when he spoke again it was on a different point.

“You sometimes jeer at me for playing the mystery-man and refusing to tell you what I infer from the facts that turn up. It's sometimes irritating, I admit; and now and again I suppose it makes me look as if I were playing the superior fellow. But it's really nothing of the sort. In affairs of this kind, one never can tell what the next turn of the wheel may be; and one might quite well blurt out something which would give the cue to the very people you want to keep in the dark.”

“You do irritate me often enough, Clinton,” Wendover admitted. “I can't see why you shouldn't put your cards on the table. A fact's a fact, after all.”

“I'll give you just one example,” said Sir Clinton seriously. “Suppose I had blurted out the fact which I'd inferred about Mme. Laurent-Desrousseaux's marriage. It was implicit in the story she told us; but luckily no one spotted the key except myself. Now, just think what would have happened to-night if that had been common property. These scoundrels would have known that Mrs. Fleetwood was legally married to young Fleetwood, since the ceremony with Staveley was illegal. Therefore, instead of trying the business of the forced marriage, they'd simply have pitched her over the cliff at the Blowhole. She'd have been dead by this time; for their only interest in keeping her alive was to force this marriage with the claimant and side-track difficulties in that way. Suppose I'd blurted out my inference, and sent that girl to her death by my carelessness, how should I be feeling at this moment? None too comfortable, so far as I can see.”

Wendover had to admit that the secrecy policy had justified itself.

“It would have been a dreadful business,” he confessed.

Inspector Armadale's figure appeared from one of the corridors, and, catching sight of Sir Clinton, he came over to where they were standing. His face showed that he had good news to tell.

“I've got practically the whole business out of them, sir. Billingford gave everything away that he knew about; and the other chap's nerve was completely gone, so that he couldn't resist questioning. It's as clear a case as one could wish for.”

He paused, as though puzzled by something, and then added:
