"It wasn't with regard to Mr. Ottershaw's cremation."

"We did what we considered to be right, and I refuse to discuss that question. For my own part, I believe if James Sims could be forced to speak the mystery would be at an end. I cannot help feeling that the police have failed in their duty by not having him arrested."

"I daresay that is a question my friend Detective Wigan will refuse to discuss," said the professor. "Do you care to hear my conditions? You can talk them over with your brother and sister when you consider whether I shall be allowed to go over the house or not."

"I shall be glad to know your fee," said Bryant.

For a moment I thought that Quarles was going to lose his temper.

"I charge no fee," he said quietly, after a momentary pause; "but if the money is found through me, you must give ten per cent. for the benefit of imbeciles according to the wish of the deceased, and you must pay me ten per cent. That will leave eighty per cent. for you to divide."

"Preposterous!" Bryant exclaimed.

"As you like. Those are my conditions, and I must receive with the permission to visit the house a properly witnessed document, showing that the three of you agree to my terms."

"I am afraid you will wait in vain."

"It is your affair," said Quarles, with a shrug of his shoulders. "Remember I can find the money, and I believe I am the only man who can."
