Gallegher stopped with a gasp and with a trembling all over his little body, and his brain asked with a throb if it could be possible. But possibilities and probabilities were to be discovered later. Now was the time for action.

He was after the man in a moment, hanging at his heels and his eyes moist with excitement.

He heard the man ask for a ticket to Torresdale, a little station just outside of Philadelphia, and when he was out of hearing, but not out of sight, purchased one for the same place.

The stranger went into the smoking-car, and seated himself at one end toward the door. Gallegher took his place at the opposite end.

He was trembling all over, and suffered from a slight feeling of nausea. He guessed it came from fright, not of any bodily harm that might come to him, but of the probability of failure in his adventure and of its most momentous possibilities.

The stranger pulled his coat collar up around his ears, hiding the lower portion of his face, but not concealing the resemblance in his troubled eyes and close-shut lips to the likenesses of the murderer Hade.

They reached Torresdale in half an hour, and the stranger, alighting quickly, struck off at a rapid pace down the country road leading to the station.

Gallegher gave him a hundred yards’ start, and then followed slowly after. The road ran between fields and past a few frame-houses set far from the road in kitchen gardens.

Once or twice the man looked back over his shoulder, but he saw only a dreary length of road with a small boy splashing through the slush in the midst of it and stopping every now and again to throw snowballs at belated sparrows.

After a ten minutes’ walk the stranger turned into a side road which led to only one place, the Eagle Inn, an old roadside hostelry known now as the headquarters for pothunters from the Philadelphia game market and the battleground of many a cock-fight.
