“It is annoying.”

Carter left the vault and started uptown.

So far, he considered that he had made very little progress with the investigation.

He reached the Humberland House, and entered the café.

It was four o’clock in the afternoon, and quite a number of men were in the place. He thought that there might be a chance of learning something here, and that was the reason why he had stopped.

The man who had given Isabella Porter’s note to the messenger he thought might come into the place. He sat down at one of the tables, and proceeded to inspect the men around him.

His attention was attracted toward a tall man who was seated at the next table, with a short, stout man.

The man was well dressed.

There was something about his manner the detective did not like, and he looked at him more closely than he otherwise would have done.

All of a sudden it came to him that this man answered the description of the man who had given the messenger boy Isabella Porter’s note.
