Old Harding and Mortlake, the latter leading and beckoning to Lieut. Bradbury, slipped cautiously through the alders, and took up a position in the clump at the edge of the road behind a big bowlder, where they could command a good view of the thoroughfare without being seen themselves. The officer, with a keener sense than ever of doing something dishonorable, joined them.

"Hark!" exclaimed Mortlake presently.

But, although they all strained their ears, they could hear no sound except the cracking of a tree limb, as it rubbed against another branch in the night wind.

"You are sure this was the place?" asked the officer.

"So my man told me," rejoined Mortlake. "You know, I relied absolutely on his word for this thing, all the way through. I, myself, know nothing of it."

He emphasized these last words, as if he wished them to stick in his hearer's memory.

Suddenly, however, a new sound struck into the silence.

It was a heavy footstep, gradually drawing closer. Round the dark corner of the road came a tall form in a long coat and with a slouch hat pulled down well over its eyes.

Lieutenant Bradbury could have groaned. Mortlake nudged him triumphantly.

"Well," he said, "I guess part of it's true, anyhow."
