"One thing more. You are evidently sure that Mr. Quadrant's body was taken out of the coffin. Do you think, then, that the coffin was empty when they took it to the crematory?"

"Why, sure! What could there be in it?"

"Suppose I were to tell you that another detective has examined the ashes and declares that he can prove that a human body was burned with that coffin. What would you say?"

"I'd say he was a liar. I'd say he was riggin' you to get you off the scent. No, sir! Don't you follow no such blind trail as that."

As Mr. Barnes left the undertaker's shop he observed Mr. Burrows coming towards him. It will be recalled that this young detective, now connected with the regular police force of the metropolis, had earlier in life been a protégé of Mr. Barnes. It was not difficult to guess from his being in this neighborhood that to him had been intrusted an investigation of the Quadrant mystery.

"Why, hello, Mr. Barnes," Mr. Burrows exclaimed, as he recognized his old friend. "What are you doing about here? Nosing into this Quadrant matter, I'll be bound."

"It is an attractive case," replied Mr. Barnes, in non-committal language. "Are you taking care of it for the office?"

"Yes; and the more I look into it the more complicated I find it. If you are doing any work on it, I wouldn't mind comparing notes."

"Very well, my boy," said Mr. Barnes, after a moment's thought, "I will confess that I have gone a little way into this. What have you done?"
