She saw Runnion gazing over his shoulder in search of a shelving beach or bar, his profile showing more debased and mean than she had ever noticed it before. They rounded a bend where the left bank crumbled before the untiring teeth of the river, forming a bristling chevaux-de-frise of leaning, fallen firs awash in the current. The short side of the curve, the one nearest them, protected a gravel bar that made down-stream to a dagger-like point, and towards this Runnion propelled the skiff. The girl's heart sank and she felt her limbs grow cold.
The mind of Poleon Doret worked in straight lines. Moreover, his memory was good. Stark's statement, which so upset Gale and the Lieutenant, had a somewhat different effect upon the Frenchman, for certain facts had been impressed upon his subconsciousness which did not entirely gibe with the gambler's remarks, and yet they were too dimly engraved to afford foundation for a definite theory. What he did know was this, that he doubted. Why? Because certain scraps of a disjointed conversation recurred to him, a few words which he had overheard in Stark's saloon, something about a Peterborough canoe and a woman. He knew every skiff that lay along the waterfront, and of a sudden he decided to see if this one was where it had been at dusk; for there were but two modes of egress from Flambeau, and there was but one canoe of this type. If Necia had gone up-river on the freighter, pursuit was hopeless, for no boatman could make headway against the current; but if, on the other hand, that cedar craft was gone--He ran out of Stark's house and down to the river-bank, then leaped to the shingle beneath. It was just one chance, and if he was wrong, no matter; the others would leave on the next up-river steamer; whereas, if his suspicion proved a certainty, if Stark had lied to throw them off the track, and Runnion had taken her down-stream--well, Poleon wished no one to hinder him, for he would travel light.
The boat WAS gone! He searched the line backward, but it was not there, and his excitement grew now, likewise his haste. Still on the run, he stumbled up to the trading-post and around to the rear, where, bottom up, lay his own craft, the one he guarded jealously, a birch canoe, frail and treacherous for any but a man schooled in the ways of swift water and Indian tricks. He was very glad now that he had not told the others of his suspicions; they might have claimed the right to go, and of that he would not be cheated. He swung the shell over his shoulders, then hurried to the bank and down the steep trail like some great, misshapen turtle. He laid it carefully in the whispering current, then stripped himself with feverish haste, for the driving call of a hot pursuit was on him, and although it was the cold, raw hours of late night, he whipped off his garments until he was bare to the middle. He seized his paddle, stepped in, then knelt amidships and pushed away. The birch-bark answered him like a living thing, leaping and dancing beneath the strokes which sprung the spruce blade and boiled the water to a foam, while rippling, rising ridges stood out upon his back and arms as they rose and fell, stretched and bent and straightened.
