"You have to face it, Mr. Ferguson. It is the more painful because it is a distorted love, a maniacal exaggerated love for you, and possibly for his dead mother, which has prompted his action. His very soul is consumed with hatred for this splendid child, whose health and beauty are a contrast to his own weakness."

"Good God! It is incredible!"

"Have I spoken the truth, madame?"

The lady was sobbing, with her face buried in the pillows. Now she turned to her husband.

"How could I tell you, Bob? I felt the blow it would be to you. It was better that I should wait and that it should come from some other lips than mine. When this gentleman, who seems to have powers of magic, wrote that he knew all, I was glad."

"I think a year at sea would be my prescription for Master Jacky," said Holmes, rising from his chair. "Only one thing is still clouded, madame. We can quite understand your attacks upon Master Jacky. There is a limit to a mother's patience. But how did you dare to leave the child these last two days?"

"I had told Mrs. Mason. She knew."

"Exactly. So I imagined."

Ferguson was standing by the bed, choking, his hands outstretched and quivering.

"This, I fancy, is the time for our exit, Watson," said Holmes in a whisper. "If you will take one elbow of the too faithful Dolores, I will take the other. There, now," he added, as he closed the door behind him, "I think we may leave them to settle the rest among themselves."
