As Alix and her friends went out to the automobile, the big police dog trotted beside Addison Blythe, looking up into his face with pleased and friendly eyes. He allowed the man to stroke his head and rumple the thick fur on his back.

"He likes you, Addison," said Alix, a serious little frown in her eyes. "I can't understand his not liking Courtney Thane. His hair fairly bristles and he growls like a bear every time he sees him. Isn't it odd?"

Blythe looked up quickly. It was on the tip of his tongue to say something tactless. What he did say was this:

"Can you blame the poor dog for being jealous?"


CHAPTER XIII — THE OLD INDIAN TRAIL

Courtney delayed. A certain aloofness on Alix's part caused him to hesitate. Something in her manner following upon the visit of the Blythes invited speculation. She was as pleasant as ever, yet he sensed a subtle change that warned him of defeat if he attempted to storm the citadel. His confidence was slightly shaken,—but not his resolve.

"She's been different ever since those infernal Blythes were here," he reflected aloud, scowling as he watched her pass in the car several days after the departure of her guests.

She went to the city nearly every day now, and seldom returned before dark. Somehow he felt that his grip was slipping. He was standing in front of the Tavern. She had waved her hand to him, and had smiled gaily, but it was not the first time that week she had failed to stop and repeat her usual invitation for him to accompany her, even though she knew he would politely decline. He resented this oversight. How could she know that he hadn't changed his mind about going to the city? As a matter of fact, he had changed it. He would have gone like a shot. Indeed, he had dressed with that very object in view,—and she had gone by with a casual wave of her hand. His annoyance was increased by the remark of Mr. Nichols, who was standing at the top of the steps at the time.
