"He's gone!" she murmured distractedly. She realized now the impossibility of finding him. His solitary habits, his dearth of friends, his lonely existence, left her without the least idea of how to commence a search. She knew, actually, so little about him--not even the source of the apparently sufficient income on which he subsisted. She felt herself completely at a loss, puzzled, lonesome, and disheartened. The futile buzzing of the telephone signal symbolized her frustration. Perhaps, she thought, Dr. Horker might suggest something to do; perhaps, even, Mueller had reported Nick's whereabouts. She seized the hope eagerly. A glance at her wrist-watch revealed the time as ten-thirty; squarely in the midst of the Doctor's morning office hours, but no matter. If he were busy she could wait. She rose, bounding hastily down the stairs. She glimpsed her mother opening mail in the library, and paused momentarily at the door. Mrs. Lane glanced up as she appeared. "Hello," said the mother. "You've been on the telephone all morning, and what did Carl want of you last night?" "Argument," responded Pat briefly. "Carl's a gem! He's been of inestimable assistance in developing you into a very charming and clever daughter, and Heaven knows what I'd have raised without him!" "Cain, probably," suggested Pat. She passed into the hall and out the door, blinking in the brilliant August sunshine. She crossed the strip of turf, picked her way through the break in the hedge, and approached the Doctor's door. It was open; it often was in summer time, especially during his brief office hours. She entered and went into the chamber used as waiting room. His office door was closed; the faint hum of his voice sounded. She sat impatiently in a chair and forced herself to wait. Fortunately, the delay was nominal; it was but a few minutes when the door opened and an opulent, middle-aged lady swept past her and away. Pat recognized her as Mrs. Lowry, some sort of cousin of the Brock pair. "Good morning!" boomed the Doctor. "Professional call, I take it, since you're here during office hours." He settled his great form in a chair beside her. "He's gone!" said Pat plaintively. "I can't reach him." "Humph!" grunted Horker helpfully. "I've tried all morning--he's always home in the morning." "Listen, you little scatter-brain!" rumbled the Doctor. "Why didn't you tell me Mueller brought you home last night? I thought he was on the job." "I didn't think of it," she wailed. "Nick said he'd have to make some preparations, and I never dreamed he'd skip away like this." "He must have gone home directly after you left him, and skipped out immediately," said the Doctor ruminatively. "Mueller never caught up with him." "But what'll we do?" she cried desperately. "He can't have gone far with no more preparation than this," soothed Horker. "He'll write you in a day or two."
