Scarcely had the words slipped from him when he heard some one cough in the shadow of the wood, a little to the left of him. At once his bearing became alert. Moving silently from tree to tree in the direction from which the sound had come, he reached a point which gave him a view of an open glade. In the middle of the glade a girl was standing looking down at the snow. He recognized her instantly. It was his hostess, Joy Gargrave.

A minute or two passed and then the girl began to move down the glade quickly. He waited until she was out of sight, and himself walked to the middle of the glade where Joy had stood looking down at the snow. Instantly he saw what had held her eyes. A dog team had been halted there. The marks of the runners were visible in the snow, even the places where the dogs had waited, half-filled with new snow, were quite clear. His practised eyes read the signs without trouble. The team had entered the glade, had apparently waited there a little time, and then had turned and departed in the direction followed by his hostess. Impulsively, he turned to follow also, but as he did so, caught sight of footmarks debouching from the trees in a direct line to the place where the sled had been halted. They were deeply marked, and as he recognized instantly were the same as those which he had been following, when the sound of the cough had attracted his attention. The person who had made them had followed a devious path, making for the glade.

He frowned to himself. The mystery was growing deeper. But as no solution of the affair offered itself to his mind, after a little delay he began to follow the sled tracks down the glade, noting that side by side with them, were the fresh tracks made by Joy Gargrave’s moccasined feet.

The glade led out into the main road from the river to the house, and the sled-tracks turned towards the river, and then were lost in the hard-packed snow of the road. But as the sled had manifestly turned in the direction of the river, Corporal Bracknell also turned that way, walking quickly and keeping a sharp look-out on either hand for any indication of the sled having turned aside.

To or three minutes’ quick walking brought him in sight of the frozen river, and at the top of the bank, seated on a fallen tree, he perceived Joy Gargrave.

Her back was towards him, and her bent head and hunched-up shoulders were eloquent of dejection. He moved towards her quietly, and as he drew nearer a flutter of white caught his eye. It was the corner of a handkerchief which the girl was holding to her face, and apparently she was crying. A quick sympathy moved him as he stepped up to her, the snow deadening his steps.

“Miss Gargrave, you are in trouble. I wonder if I can be of any assistance?”

Startled by the sound of his voice, the girl looked up, and for one fleeting moment he had a vision of the beautiful face, tear-stained, and of the blue eyes full of trouble. Then the face was hidden in the handkerchief again, and a succession of sobs was the only answer vouchsafed to him. He stood for a little while in silence, looking down at the shaking shoulders. His own eyes filled with sympathetic concern, then he spoke again.

“Please, Miss Gargrave. Let me help. I am sure your trouble is very grave.”
