devoted your life to." Ish could feel his jaw muscles bunching. "Don't put words in my mouth!" he snapped. "Just get me back, and we'll split hairs about it when I get around this way again." Suddenly, he found himself pleading. "All I need is a week," he said. "It'll be a rough week—no picnic, no pleasures of the flesh. No smoking, no liquor. I certainly won't be breaking any laws.
