It gets difficult to handle the problem of a man who has a real talent that you need badly—and he cannot use it if he knows it's honest!
There was no one standing or sitting around the tastefully furnished entry hall of the Institute of Insight when Wallace Cavender walked into it. He was almost half an hour late for the regular Sunday night meeting of advanced students; and even Mavis Greenfield, Dr. Ormond's secretary, who always stayed for a while at her desk in the hall to sign in the stragglers, had disappeared. However, she had left the attendance book lying open on the desk with a pen placed invitingly beside it.
Wallace Cavender dutifully entered his name in the book. The distant deep voice of Dr. Aloys Ormond was dimly audible, coming from the direction of the lecture room, and Cavender followed its faint reverberations down a narrow corridor until he reached a closed door. He eased the door open and slipped unobtrusively into the back of the lecture room.
As usual, most of the thirty-odd advanced students present had seated themselves on the right side of the room where they were somewhat closer to the speaker. Cavender started towards the almost vacant rows of chairs on the left, smiling apologetically at Dr. Ormond who, as the door opened, had glanced up without interrupting his talk. Three other faces turned towards Cavender from across the room. Reuben Jeffries, a heavyset man with a thin fringe of black hair circling an otherwise bald scalp, nodded soberly and looked away again. Mavis Greenfield, a few rows further up, produced a smile and a reproachful little headshake; during the coffee break she would carefully explain to Cavender once more that students too tardy to take in Dr. Al's introductory lecture missed the most valuable part of these meetings.
