“Did you see his face?”

“No, I didn’t. But from the man’s general appearance I could have sworn it was he. This is two murders that Weeden has been guilty of to-day. The first was poor Sweet; the second the driver of the ambulance,” said Nick.

“It was a mighty lucky thing for you that the driver stepped in front of you just as he did, or we should not have had the services of Nick Carter, the famous detective, at our disposal now.”

“Yes, the poor fellow saved my life,” said Nick. “The bullet evidently was meant for me.”

The doctor, having finished his work, bade the detectives good night.

After he had gone they walked slowly up the street. A taxicab was driving by the corner. Nick and Inspector Ward hailed the chauffeur. Having made a bargain with him, they directed him to drive them to Weeden’s shop.

He looked at them very hard. It was evident that he had recognized them, and had purposely thrown himself in their way. If they had seen the gleam in the chauffeur’s eye, as he made a motion to three men who stood in the shadow of a doorway on the other side of the street, they would have been on their guard.

They did not see it, however.

The vehicle was driven rapidly in the direction of Grant Avenue. The machine had not left the corner more than a couple of minutes when a taxicab surrey with drawn curtains drove up.

The three men who had been standing on the other side of the street jumped in and drove in the direction of the vehicle occupied by the inspector and Nick Carter.
