“Ah! I understand; you, like the others, think he is guilty,” she said in a tone of bitter reproach. “Some enemy has denounced him and set the bloodhounds of the law upon him. They will follow the scent, and soon discover him. But is he guilty?”

“I can only tell you one fact, Dora, much as I regret it,” I answered. “The detective who has the case in hand, one of the most renowned experts in his profession, holds evidence against him of a most conclusive character.”

“In what way? What is the nature of the evidence?” she demanded.

“There is a witness,” I replied slowly. “A person discovered Gilbert lying dead in Jack’s chambers immediately after the crime. On the following night the same person visited the place secretly, and there met Jack, who was apparently engaged in getting rid of all traces of the murder. This witness desired to enter one of the rooms, but Jack locked the door in his face. In that room it will be proved the body of the murdered man was still lying.”

“It will not be so easy to prove that last fact as you imagine,” she said very seriously.

“Then Jack has already told you the truth!” I exclaimed.

“He told me something before—before I fell ill,” she answered.

It was on my lips to ask her for an explanation of the cause that led to her brain-trouble, but, remembering the strict injunctions of the great specialist, I deferred my question.

“Then you believe he is innocent?” I asked eagerly.

“The police may bring forward an array of whatever witnesses they choose, but I will show them that Jack is no murderer,” she said firmly. “I do not wonder that you, in common with others, suspect him, but when the truth is made clear you will be amazed at the villainy that has been resorted to by those responsible for Sternroyd’s death.”
