"Well, gentlemen, we must go back to town at once, and see Lord Calliston. I want an account of all his movements on that night, and I already know where he was at nine o'clock."

"Where?" asked Norwood, curiously.

"At the 'Pink 'Un,' Soho, to see a boxing-match--afterwards I don't know where he went, but I must have a satisfactory explanation."

"But you don't think he murdered Lady Balscombe?" said the baronet.

Dowker looked wise.

"No," he replied, significantly, "I don't think he murdered Lady Balscombe, but he might have murdered Lena Sarschine."

"You mean he might have mistook my wife for his mistress."

"Exactly!"
