"Geoffrey!" she cried, joyfully.

"Yes; I wonder why he did not send me notice of his coming. He wants to see me on business. Business!" he repeated, with a frown. "Humph! I hope he has found no new mare's nest with your assistance."

"I have meddled no more with the case, papa, if that is what you mean," said Miss Cass. "But where is he?"

"In the library. I will see him first. You can talk to him afterwards."

"Ask him to stay, papa," said Ruth, following her father to the door of the dining-room.

"Of course he can stay if he likes," Mr. Cass said, looking at his daughter as if he were about to make some remark. However, he thought better of it and hurried out. Ruth guessed that it had been in his mind to say something about the unhappy affair in which they were all interested. She was irritated at not being admitted into his confidence, for her nerves were worn thin with the constant strain. However, he had been quite determined to see Geoffrey alone; and all she could do was to possess herself in patience until such time as the conversation should have ended.

Meanwhile the two men were sitting opposite one another in Mr. Cass's room. Geoffrey refused to have any dinner; he had dined before leaving home, he said, but he did not decline a cigar and glass of good port. Mr. Cass was at once convinced, from the expression of tragic gravity on the young man's face, that he had something serious to say, and he concluded that it had to do with the Jenner case. But he was not going to commit himself by introducing the subject lest he might appear too eager. He talked lightly on desultory matters and waited for Heron to begin.

"Mr. Cass," he said, at last, "I have come to renew our former conversation."

"Oh, the Jenner murder, I suppose?" Mr. Cass said, lightly. "I thought as much; but I did not know that you intended to pursue the matter."

"Nor did I of my own free will," replied Geoffrey, coolly; "but circumstances have thrust upon me fresh discoveries, and I want your assistance."
