"Yes."

"To establish what?"

"That he is a pure young man and has been wronged. I really believed he would be with the burglars. You are to establish the fact that he instigated the robbery, that these men are his pals, as you detectives call them, and you are to follow him up and establish his career as a professional thief and criminal."

"I must find him first."

"Yes, you must find him, and I think you will succeed. You have his photograph; it is an excellent picture; when she got it I don't know, and I tell you it was hard for me to dissimulate yesterday, but I do not desire her to know that I suspect, even when we have all the proofs, and want it to come as a revelation to her. I never wish her to know that I ever suspected the truth."

"Madam, I will undertake to establish the fact that this young man is a criminal, or the victim of cruel suspicions."

"He is a criminal, I am sure of it."

"One moment; do you wish it to be established that he is a criminal, whether he is or not?"

The detective fixed a keen look on Mrs. Frewen's face as he asked the question. A moment the old lady hesitated and then said:

"Yes."
