“Hello!” was his exclamation.

His eyes had fallen upon a name.

“Joseph Gregory Leslie.”

Turning the card over he found, scribbled in pencil, the words:

“Called to see you—may come in later to-night. Some important business.”

When he had read this the detective scratched his head and mused.

“How is this—he must have run down here first. Come in later, eh? Well, who knows but what after he has seen Marian home he may run down?”

He stopped to listen to a carriage rumbling along the street—at this time of night they were not very frequent here, and when it stopped in front of the house he smiled.

“Ah, he has seen her home and come down to carry out his promise to Lillian. The story of the erring clerk may not be all moonshine.”

He put his head out of the window.
