Mr. Flexen did not try to interview her again. But at eleven the next morning he called on Mr. Manley. He had very little hope of effecting anything by the call, though he meant to try. But he had the keenest desire to scrutinize him again and carefully in the light of the new facts he had discovered.

Mr. Manley kept him waiting awhile in the drawing-room; then the maid ushered him into Mr. Manley's study. Mr. Manley was sitting at a table, at work on his play. He greeted Mr. Flexen with a rather absent-minded air.

Mr. Flexen surveyed him with very intent, measuring eyes. At once he perceived that he had rather missed Mr. Manley's jaw in giving attention to his admirable forehead. It was, indeed, the jaw of a brute. He could see him drive the knife into Lord Loudwater, and walk out of the smoking-room with an ugly, contented smile on his face.

He had little hopes of bringing off anything in the nature of a bluff; but he said, in a rasping tone: "We've discovered that the signature of Lord Loudwater's letter of instructions to his bankers to pay that cheque for twelve thousand pounds into your wife's account was forged."

Mr. Manley looked at him blankly for a moment. There was no expression at all on his face. Then it filled slowly with an expression of surprise.

"Rehearsed, by Jove!" murmured Mr. Flexen under his breath, and he could not help admiring the skilful management of that expression of surprise. It was so unhasty and natural.

"My dear fellow, what on earth are you driving at? I saw him write it myself," said Mr. Manley in an indulgent tone.

"You forged it," snapped Mr. Flexen.

Mr. Manley looked at him with a new surprise which changed slowly to pity. Then he said in such a tone as one might use to an unreasonable child: "My good chap, what on earth should I forge it for?"

"You knew that he was going to halve Mrs. Truslove's allowance. You were bent on marrying a woman with money. You took this way of ensuring that she had money, forged the letter, and murdered Lord Loudwater," said Mr. Flexen on a rising inflexion.
