"Is he in town now?"

"I believe so. My nephew, Theodore Dane, told me that he had seen him over a week ago. Harry then said that he had returned from the Far East, and was going later to Amsterdam for a few days. If he has carried out his intention I expect that he is ignorant of his mother's death."

"When he hears of it will he return?"

"Immediately, I think, as Harry is greatly attached to, his mother. If anyone can find the assassin, Harry Pentreddle will, as he is smart, and very tenacious of anything he takes up. I wish I knew where he was in Amsterdam, Miss Carrol, as I could then send him a telegram."

Patricia pondered. "I wonder if he can throw any light on the motive for the commission of the crime?"

"It seems impossible, as Harry, having been on a year's voyage, has not seen his mother for twelve months. It is just possible that, as Martha was a week in town before her murder, she may have seen Harry in the interval. Of course, I understand that Martha only sprained her foot on the night previous to her death."

"She slipped on the stairs," said Patricia mechanically. "Her son certainly has not been here, or Mrs. Sellars would have told me. Have you any idea what caused the crime to be committed?"

Mr. Colpster pondered in his turn. "I rather think I will wait until the inquest is ended before answering that question," he said judicially.

"But won't you answer it at the inquest, so that the truth of the matter may be known," urged the girl, puzzled by his tone.

"I may not be asked the question at the inquest," said Mr. Colpster blandly, and declined to discuss the matter further. Indeed, there was no time, as they were summoned at this moment to the drawing-room, where the jurymen, under the control of the coroner, were waiting for the various witnesses. They had already inspected the body of the unfortunate woman, which was lying in an upstairs bedroom.
