"Would you object to telling me what others share your extraordinary opinion?"
"I did not say that it is my opinion. More than that, I will say that it is not my opinion, not at present at all events. But it is the view which is receiving close attention at police headquarters."
"Are you one of the detectives?"
"I am a detective, but not connected with the city force."
"Then by what right do you intrude yourself into this affair?"
Mr. Barnes knew that he must play his best card now, to gain his point with this man. He watched him closely as he answered:
"I am employed by Mrs. Quadrant."
There was an unmistakable start. Amos Quadrant was much disturbed to hear that his sister-in-law had hired a detective, and curiously enough he made no effort to hide his feelings. With some show of emotion he said in a low voice:
"In that case, perhaps, we should better have a talk together. Come in."
With these words he led the way into the house, and invited the detective into the same room wherein he had talked with Mark Quadrant. When they had found seats, Mr. Quadrant opened the conversation immediately.
