It was comparatively early in the evening. There were not enough moon-rays to show the face of his watch, but it could not be ten o’clock. A light was burning within the structure, whose interior was hidden by a curtain drawn across each of the two windows,—one on either side of the door. All was silent, and the peering eyes detected no sign of life on the outside.

It was not to be supposed that the abductors of little Grace Hastings would maintain a guard at the cabin itself. Their pickets were at a distance, and unless they gave timely notice of the approach of danger, it would be fatal to the plans of the criminals.

“I wonder whether they keep a dog,” was the thought which held the watcher motionless for a little while; “if they do, he’ll play the mischief with me.”

Could he have been assured that a canine was on watch, the detective would not have dared to go a step nearer the dwelling, but would have made all haste to Chesterton and arranged for his raid, since discovery at this stage of the game would be the end of hope.

“It strikes me that if they have a dog on guard, he ought to have discovered me by this time—Thunderation! there he comes now!”

A canine as large as a wolf came trotting across the clearing, heading directly for Simmons Pendar. It was useless to run, for the terrible brute would have been at his heels in an instant. He laid his hand on his revolver.

“If he attacks, I’ll shoot him and then the fat will be in the fire.”

While the dog was several paces away and after Pendar had drawn his weapon from his hip pocket, he spoke in soothing tones to him. The animal did not bark or growl, but seemed to be pleased by his friendly greeting. He came on, and the man never used his persuasive powers more skilfully. He called him all the pet names he could think of, and when the brute was within reach, reached out and patted his head.

To his pleased astonishment, he completely won the good will of the dog, which wagged his bushy tail so energetically that it swayed his haunches. He whined, snuffed about the man’s knees, and then abruptly raised one of his big paws, which the eavesdropper was instant to seize and shake.

“Bully for you!” exclaimed Pendar in a guarded voice; “I don’t know that your owner would be pleased with your performance, but I’m mighty sure I am.”
