The detective put two and two together and at once concluded that the man who had been watching him during the afternoon was the foe of the so-called Argetti. This man had been watching our hero because he believed he was in communication with Argetti, or the individual whom the so-called Argetti represented.

The detective meditated and finally said:

"I must see Argetti."

"You fully comprehend what I have said?"

"I do."

"You know there is risk?"

"I do."

"You know that I have advised you in all sincerity?"

"Yes."

"Do you really go alone to meet Argetti?"
