“Look inside. I guess that tells; ha, ha!” and the messenger whisked around the nearest corner and disappeared.
Already the hands of Carter had broken the seal of the missive thus strangely delivered, and in a moment he had read:
“Could you spare me five minutes of your valuable time, Mr. Carter? I can make some dark places clear to you. I can enlighten you about some important things. Come secretly, for it is ticklish business. I will be there. Come to Number — Hester Street. Don’t knock! just open the door and come to the first room on the left of the hall.
“Sara P——”
Nick Carter read the letter twice before he looked up again.
He did not know Sara P——.
He had never heard of such a person, and he racked his brain in vain to think who she might be.
He did not know what “dark places” she referred to.
She might mean some old trail which he had run down, or she might have reference to Mother Flintstone’s taking off.
The detective was puzzled.
