He was betraying it now. His clear, red-brown eyes were clouded. The healthy pink of his youthful cheeks had deepened to an unbecoming flush. His wide, engaging grin, the grin of a friendly bulldog, was lacking, and his lips were set tight. Even his burnished red pomadour added to the general pugnaciousness of his appearance. Standing up at its most aggressive angle, it seemed to challenge the world. Sitting on a low chair in the dressing-room of the bachelor apartment he and Laurence Devon occupied together, Rodney drew on a shoe and stamped his foot down into it with an emphasis that shook the floor. Devon, fastening his tie before the full-length mirror set in the door leading to their common bath-room, started at the sound, like a high-strung prima donna. This was one of Laurie's temperamental mornings. "What the devil's the matter with you, Bangs?" he demanded, but without ill humor. "Can't you get on a shoe without imitating the recoil of a seventy-five centimeter gun?" Bangs grunted, drew on the other shoe, and drove his foot into it with increased energy. Laurie looked at him, and this time there was a spark in his black eyes. Very quietly he turned, crossed the small room, and, planting himself in front of his chum, resentfully stared down at the dynamic youth. "What's the idea?" he demanded. "Are you deliberately trying to be annoying?" Rodney did not raise his head. His fingers were busy with a complicated knot. "Oh, shut up!" he muttered. Laurie, his hands in his pockets, remained where he was. Under his continued inspection, the fingers of Bangs grew clumsy. He fumbled with the knot, and, having unfastened it, prolonged to the utmost the process of lacing his shoes. He knew what must come as soon as he settled back in his chair. It had been coming for days. He was in for an unpleasant ten minutes. But the situation was one he had deliberately created as the only possible way of bringing about a serious talk with his friend. Now that it was here, he was anxious to make the most of it. With head bent and thoughts busy he played for time. At last, the shoes laced and his campaign mapped out, he sat up and met Laurie's eyes. Their expression of antagonism, temporary though he knew it to be, hurt him. Devon, when he had his own way, and he usually had it, was a singularly sweet-tempered chap. Never before, throughout their year of close association, had he looked at Bangs like that. Rodney knew that he deserved the look. For days past he had deliberately subjected his companion to a series of annoyances, small but intensely irritating. "Well?" demanded Laurie. "What's the answer?" "What answer?" Rodney was in the position of a small boy challenged to combat in cold blood. He was experiencing some difficulty in working himself up to the necessary heat for an engagement. But Laurie's next words helped him out. "You've been making a damned nuisance of yourself for the last week," he said deliberately. "I want to know why."
