Dickson, always nervous being late for trains, forced his eyes away and regarded again the road behind him.

Suddenly the cyclist had become quite plain--a little more than a mile behind--a man, and pedalling furiously in spite of the stiff ascent.

It could only be one person--Leon.

He must have discovered their visit to the House yesterday and be on the way to warn Dobson.

If he reached the station before the train, there would be no journey to Glasgow that day for one respectable citizen.
Dickson was in a fever of impatience and fright.
