"Ah! You refuse to help me?"
"Oh, no! no! I shall only be too glad to do what I can," protested Lucian, shocked that she should think him so hard-hearted, "but I know of nothing likely to solve the mystery. Both myself and Link have done our best to discover the truth, but without success."
"Well, Mr. Denzil," said Diana, after a pause, "they often say that a woman's wit can do more than a man's logic, so you and I must put our heads together and discover the guilty person. Have you no suspicion?"
"No. I have no suspicion," replied Lucian frankly. "Have you?"
"I have. I suspect—a lady."
"Mrs. Vrain?"
"Yes. How do you know I meant her?"
"Because at one time I suspected her myself."
"You suspected rightly," replied Diana. "I believe that Mrs. Vrain killed her husband."
