"It solves a good many things, however," said Dowker, cheerfully, "it proves the truth of Mr. Desmond's statement about the dagger, and shows us how it was Lady Balscombe went to Lord Calliston's chambers instead of Miss Sarschine--I beg pardon, Lady Calliston--but tell me, madame, did your husband know of the murder before he left England?"

"No; how could he?" she said, in surprise. "He came down to Shoreham by an early train and the yacht left at once."

"But he would be sure to see about it in the morning papers?" suggested Norwood.

"He would only see the announcement, but no details," said Dowker, "and thinking Lady Balscombe was on board the yacht, and Miss Sarschine at home, he would never think either of them was the victim."

"Well, gentlemen," said Sir Rupert, turning his haggard face towards them, "now we have discovered the dead woman to have been my wife, what is the next thing to be done?"

"See Lord Calliston," answered Dowker, promptly. "I want to know all his movements on that night."

"You don't suspect him," said Lena, turning on him like a tiger.

"I never said I did," he replied quietly. "I merely want to find out his movements, and I daresay he'll have no hesitation in giving an account of them."

"Of course he won't," she replied wearily, "and now, as I've told you all, you'll permit me to retire. I'm quite worn out."

She bowed to the three men, then left the cabin slowly. When she disappeared, Dowker shook himself briskly.
