A little later, he had seen the men cross the road toward the upper field.

Then, almost on the men's heels, he had seen Bruce and Wolf canter across the same road; headed for the forest.

And Dugan's correctly stolid face rippled into a pleased smile.
Quickening his pace, he hurried on to the gateway and down the drive.
But, as he passed the house on his way to the garage where stood the other and larger car, he paused.

Out of an ever-vigilant eye-corner, he saw an automobile turn in at the gateway, two hundred yards up the wooded slope; and start down the drive.
The Mistress and the Master were returning from the post office.
Dugan's smile vanished.

He stopped in his tracks; and did some fast thinking.
