the inside. It had to be broken open. Perhaps you heard of the case?"

Quarles shook his head.

"Well, the door was locked on the inside, the window was shut and
fastened, there was no sign that any one had entered the room, and
nothing was missing. Foul play was out of the question, but the doctor
who was called in was troubled about the affair. It was from him that I
had these particulars. Dr. Bates had become acquainted--not
professionally, I believe--with the young couple who had lived in the
house for a time, and they had told him the place was haunted. In
bringing his judgment to bear upon Greaves' death, it is only right to
remember that his mind had received a bias."

"I take it he did not believe it was a case of suicide," said Quarles.

"His reason told him it must be, yet something beyond reason told him
it wasn't."

"He thought it was murder?" I asked.

"No, not ordinary murder," Randall answered. "He thought it was a
supernatural death."

"I have read the letter he wrote to you; there is nothing very definite
in it," said Quarles.

"It was his indefinite state of mind which caused him to relate the whole
story to me. When the police failed to make any discovery, he thought
some one interested in psychological research might solve the mystery."
