She went on toward the hospital gateway and had scarcely recovered her self-control when she arrived there. Altogether, her evening's experience had been most disconcerting.

The two men, dressed alike and apparently of the same height and shambling manner, whom she had seen in Nicko's garden, worried her quite as much—indeed, worried her even more than the sight of the mysterious creature the peasants called the werwolf.

More than ever was she determined to take into her confidence somebody who would be able to explain the mystery of it all. At least, he would be able to judge if what made her so anxious was of moment.

And Tom Cameron's disappearance, too! Ruth's worry of mind regarding her old friend propped her eyes open that night.

In the morning she went over the stock shelves again with the girl she had trained, and finally announced to Mrs. Strang that she felt she must return to Clair. After all, she had been assigned to the job there and must not desert it.

An ambulance was going down to Clair with its burden of wounded men, and Ruth was assigned to the seat beside the driver. He chanced to be "Cub" Holdness, one of the ambulance drivers to whom Ruth had been introduced by Charlie Bragg at Mother Gervaise's cottage the night of her trip up to the field hospital.

Holdness was plainly delighted to have the girl with him for the drive to Clair. He was a Philadelphia boy, and he confessed to having had no chance to drive a girl—even in an ambulance—since coming over.

"I had one of those 'reckless roadsters' back home," he sighed. "Dad said every time his telephone rang he expected it was me calling from some outlying police station for him to come and bail me out for overspeeding.

"And there was a bunch of girls I knew who were just crazy to have me take 'em for a spin out around Fairmount Park and along the speedways. Just think, Miss Fielding, of the difference between those times and these," and he nodded solemnly.

"I should say there was a difference," laughed Ruth, trying to appear in good spirits. "Don't you get dreadfully tired of all these awful sights and sounds?"
