By the time Thompson decided that in common decency he should offer to lend a hand and thus was moved to rise and approach the disabled car she had the jack under the front axle and was applying a brace wrench to the rim bolts. But the rim bolts that hold on a five-inch tire are not designed to unscrew too easily. Sophie had started one with an earnest tug and was twisting stoutly at the second when he reached her. He knew by the impersonal glance she gave him that he was to her merely a casual stranger.

"May I help you?" he said politely. "A big tire is rather hard to handle."

Sophie bestowed another level look upon him as she straightened up from her task. A puzzled expression showed briefly in her gray eyes. But she handed him the wrench without parley.

"Thanks, if you will," she said. "These rim bolts are fearfully stiff. I daresay I could manage it though. I've done it on a lighter car. But it's a man's job, really."

Thompson laid off his coat and set to work silently, withholding speech for a double reason. He could not trust his tongue, and he was not given to inconsequential chatter. If she did not recognize him—well, there was no good reason why she should remember, if she chose not to remember. He could lend a hand and go his way, just as he would have been moved to lend a hand to any one in like difficulty.

He twisted out the bolt-heads, turned the lugs, pulled the rim clear of the wheel. He stood up to get the spare tire from its place behind. And he caught Sophie staring at him, astonishment, surprise, inquiry all blended in one frank stare. But still she did not speak.

He trundled the blow-out casing to the rear, took off the one ready inflated, and speedily had it fast in its appointed position on the wheel.

And still Sophie Carr did not speak. She leaned against the car body. He felt her eyes upon him, questioning, appraising, critical, while he released the jack, gathered up the tools, and tied them up in the roll on the running board.

"There you are," he found himself facing her, his tongue giving off commonplace statements, while his heart thumped heavily in his breast. "Ready for the road again."

"Do you remember what Donald Lachlan used to say?" Sophie answered irrelevantly. "Long time I see you no. Eh, Mr. Thompson?"
