Below the hotel was the Serpentine Coast, a long and dangerous course, full of high-banked curves, of sudden descents, of long straightaway dashes through the woodland. Two miles, perhaps three, it wound its tortuous way down the mountain. Up by the highroad to the crest again, only a mile or less. Thus it happened that the track was always clear, except for speeding sleds. No coasters, dragging sleds back up the slide, interfered.
The track was crowded. Every minute a sled set out, sped down the straightaway, dipped, turned, disappeared. A dozen would be lined up, waiting for the interval and the signal. And here, watching from the porch of the church, in the very shadow of the saints, Marie found her revenge.
Stewart had given her a little wrist watch. Stewart and Anita were twelfth in line. By the watch, then, twelve minutes down the mountain-side, straight down through the trees to a curve that Marie knew well, a bad curve, only to be taken by running well up on the snowbank. Beyond the snowbank there was a drop, fifteen feet, perhaps more, into the yard of a Russian villa. Stewart and Anita were twelfth; a man in a green stocking-cap was eleventh. The hillside was steep. Marie negotiated it by running from tree to tree, catching herself, steadying for a second, then down again. Once she fell and rolled a little distance. There was no time to think; perhaps had she thought she would have weakened. She had no real courage, only desperation.
As she reached the track the man in the green stocking-cap was in sight. A minute and a half she had then, not more. She looked about her hastily. A stone might serve her purpose, almost anything that would throw the sled out of its course. She saw a tree branch just above the track and dragged at it frantically. Some one was shouting at her from an upper window of the Russian villa. She did not hear. Stewart and Anita had made the curve above and were coming down at frantic speed. Marie stood, her back to the oncoming rush of the sled, swaying slightly. When she could hear the singing of the runners she stooped and slid the tree branch out against the track.
She had acted almost by instinct, but with devilish skill. The sled swung to one side up the snowbank, and launched itself into the air. Marie heard the thud and the silence that followed it. Then she turned and scuttled like a hunted thing up the mountain side.
Peter put in a bad day. Marie was not about, could not be located. Stewart, suffering from concussion, lay insensible all day and all of the night. Peter could find no fracture, but felt it wise to get another opinion. In the afternoon he sent for a doctor from the Kurhaus and learned for the first time that Anita had also been hurt--a broken arm. "Not serious," said the Kurhaus man. "She is brave, very brave, the young woman. I believe they are engaged?" Peter said he did not know and thought very hard. Where was Marie? Not gone surely. Here about him lay all her belongings, even her purse.
