Simon by J. Storer Clouston

It was on this same evening that Superintendent Sutherland was almost rewarded for his vigilance by having something distinctly suspicious to report. As it happened, it proved a disappointing incident, but it gave the superintendent something to think about.

He was going a few stations down the line to investigate a rumour of a suspicious person seen in that neighbourhood. It was a vague and improbable rumour and the superintendent was setting out merely as a matter of form, and to demonstrate his vigilance and almost abnormal sense of duty. Darkness had already fallen for an hour or two when he strode with dignified gait down the platform, exchanging a greeting with an acquaintance or two, till he came to the front carriage of the train. He threw open the door of the rear compartment, saw that it was empty, and was just going to enter when glancing over his shoulder he perceived his own cousin Mr. MacAlister upon the platform. Closing the door, he stepped down again and greeted him.
