And it was at that moment that there came a ring at the front-door bell. There was a brief altercation; then Jimmy’s man appeared. “Two—er—persons say you told them——” he began, when Lethbridge cut him short. “Show them in at once,” he said briefly, and his man went out again. “You’ve got to remember, Bill,” said Jimmy as they waited, “that Peter Staunton is literally, at the moment, a low-class Cockney.” Mainwaring nodded, and drew back a little as Peter and the girl came into the room. He wanted to leave the talking to Jimmy, while he watched. “Good evening, Lizzie,” Lethbridge smiled at the girl reassuringly. “I’m glad you came.” “Who’s that cove?” demanded the girl suspiciously, staring at Mainwaring. “A doctor,” said Jimmy. “I want him to have a look at Peter later on.” “His name ain’t Peter,” muttered the girl sullenly. “It’s Bill.” “Well, at Bill, then. Don’t be frightened, Lizzie; come farther into the room. I want you to see a photograph I’ve got here.” Like a dog who wonders whether it is safe to go to a stranger, she advanced slowly, one step at a time; while Peter, twirling his cap awkwardly in his hands, kept beside her. Once or twice he glanced uneasily round the room, but otherwise his eyes were fixed on Lizzie as a child looks at its mother when it’s scared. “My God, Jimmy!” whispered the doctor, “there’s going to be as big a sufferer as you if we’re successful.” And he was looking as he spoke at the girl, who, with a sudden instinctive feeling of protection, had put out her hand and taken Peter’s. Like a pair of frightened children they crept on until they came to the photograph; then they stopped in front of it. And the two men came a little closer. It was the girl who spoke first, in a low voice of wondering awe: “Gawd! it’s you, Bill—that there bloke in the frame. You were a blinking orficer.” With a look of pathetic pride on her face, she stared first at the photograph and then at the man beside her. “An orficer! Bill—an orficer! What was ’is regiment, mister?” The girl swung round on Jimmy. “Was ’e in the Guards?” “No, Lizzie,” said Lethbridge. “Not the Guards. He was in the cavalry. The 9th Hussars,” and the man, who was holding the frame foolishly in his hands, suddenly looked up. “The Devil’s Own, Peter,” went on Lethbridge quietly. “C Squadron of the Devil’s Own.” But the look had faded; Peter’s face was blank again. “I don’t remember, guv’nor,” he muttered. “And it’s making me ’ead ache—this.” With a little cry the girl caught his arm, and faced Lethbridge fiercely. “Wot’s the good of all this?” she cried. “All this muckin’ abaht? Why the ’ell can’t you leave ’im alone, guv’nor? ’E’s going to ’ave one of ’is ’eads now—’e nearly goes mad, ’e does, when ’e gets ’em.” “I think, Lizzie, that perhaps I can cure those heads of his.” It was Mainwaring speaking, and the girl, still holding Peter’s arm protectingly, looked from Lethbridge to the doctor.
