The next day he lay abed luxuriously for a while after he had awakened, but no amount of quiet thinking availed to clarify the mystery. There were two men, one bearded, interested in watching McGuire, another with a black mustache, interested in Peter. And so, after wondering again for some puzzling moments as to how Mrs. Bergen, the housekeeper, had come to be involved in McGuire's fortunes, he gave the problem up.

Foreseeing difficulties over breakfast at the house, he had arranged to make his own coffee on a small oil stove which happened to be available, and so Peter set the pot on to boil and while he dressed turned over in his mind the possibilities of the future. It seemed quite certain that the antagonism, whatever its nature, between his employer and the prowling stranger must come to an issue of some sort almost at once. The intruder, if he were the sort of man who could inspire terror, would not remain content merely to prowl fruitlessly about with every danger of being shot for his pains, and McGuire could hardly remain long in his present situation without a physical or mental collapse.

Why hadn't McGuire taken flight? Why indeed had he come to Black Rock House when it seemed that he would have been much safer amongst the crowds of the city, where he could fall back upon the protection of the police and their courts for immunity from this kind of persecution?

Pieced together, the phrases his employer had let slip suggested the thought that he had come to Black Rock to escape publicity in anything that might happen. And McGuire's insistence upon the orders that the guards should shoot to kill also suggested, rather unpleasantly, the thought that McGuire knew who the visitor was and earnestly desired his death.

But Mrs. Bergen could have no such wish, for, unlike McGuire, she had shown a reticence in her fears, as though her silence had been intended to protect rather than to accuse. Beth Cameron, too, was in some way unconsciously involved in the adventure. But how? He drank his coffee and ate his roll, a prey to a very lively curiosity. Beth interested him. And if Aunt Tillie Bergen, her only near relative, showed signs of inquietude on the girl's account, the mysterious visitor surely had it in his power to make her unhappy. As he washed up the dishes and made his bed, Peter decided that he would find Beth to-night when she came back from work and ask her some questions about her Aunt Tillie.

Beth Cameron saved him that trouble. He was sitting at the piano, awaiting a telephone call to Black Rock House, where he was to have a conference with his employer on the forestry situation. He was so deeply absorbed in his music that he was unaware of the figure that had stolen through the underbrush and was now hidden just outside the door. It was Beth. She stood with the fingers of one hand lightly touching the edge of the door-jamb, the other hand at her breast, while she listened, poised lightly as though for flight. But a playful breeze twitched at the hem of her skirt, flicking it out into the patch of sunlight by the doorsill, and Peter caught the glint of white from the tail of his eye.

The music ceased suddenly and before Beth could flee into the bushes Peter had caught her by the hand.

Now that she was discovered she made no effort to escape him.

"I—I was listening," she gasped.

"Why, Beth," he exclaimed, voicing the name in his thoughts. "How long have you been here?"
