"The plan's not very clever," Shillito rejoined. "If I made trouble for the hotel porters, the guests would wonder, and when people have nothing to do but loaf, they like to talk. I expect you'd find their curiosity awkward—" He paused and laughed when he resumed: "You're embarrassed now because somebody will see us!"

Barbara was embarrassed. A man was coming up the path, and she knew her figure and Shillito's cut against the light. When the stranger reached the veranda he would see she was disturbed; but to move back into the gloom, where Shillito would follow her, would be significant. She thought he meant to excite the other's curiosity.

The man stopped for a moment at the bottom of the steps and Barbara turned her head, since she imagined he would think she was quarreling with her lover. Then he ran up the steps, and when he stopped in front of Shillito her heart beat fast. It was Lister, and she knew he had remarked her strained look, for his face was very stern.

"Hallo!" he said. "Are you bothering Miss Hyslop again?" He glanced at Barbara. "I expect the fellow is bothering you?"

For a moment Barbara hesitated, but she had borne a heavy strain and her control was going. Besides, one could trust Lister and he knew ... She signed agreement and he touched Shillito.

"Get off the veranda!"

Shillito did not move. His pose was tense and he looked malevolent.

"You won't help Miss Hyslop by butting in like a clumsy fool. The thing's too delicate for you to meddle—"

"Get off the veranda!" Lister shouted, and threw Shillito back.

He was highly strung, and worn by want of sleep and exhausting labor, but he had some notion of all Barbara had borne on Shillito's account. Although perhaps caution and tact were indicated, he was going to use force. When Shillito struck him he seized the fellow, and rocking in a savage grapple, they fell with a crash against the rails. Lister felt the other's hand at his throat, and straining back, jerked his head away while he tried to lift his antagonist off the ground. He pulled him from the rails and they reeled across the veranda and struck the wall.
