"Dr. Ormond," Cavender said, "you're under arrest. The immediate charge, let's say, is practicing medicine without a license. Don't worry about whether we can make it stick or not. We'll have three or four others worked up by the time we get you downtown."

For a moment, there was a shocked, frozen stillness in the lecture room. Dr. Ormond's hand began to move out quietly towards the checks lying on the table before him. Reuben Jeffries' big hand got there first.

"I'll take care of these for now, Dr. Al," Jeffries said with a friendly smile. "The lieutenant thinks he wants them."

Not much more than thirty minutes later, Cavender unlocked the door to Dr. Ormond's private office, went inside, leaving the door open behind him, and sat down at Ormond's desk. He rubbed his aching eyes, yawned, lit a cigarette, looked about in vain for an ashtray, finally emptied a small dish of paper clips on the desk and placed the dish conveniently close to him.

There had been an indignant uproar about Dr. Al's arrest for a while, but it ended abruptly when uniformed policemen appeared in the two exit doors and the sobering thought struck the students that any publicity given the matter could make them look personally ridiculous and do damage to their business and social standing.

Cavender had calmed their fears. It was conceivable, he said, that the district attorney's office would wish to confer with some of them privately, in connection with charges to be brought against William Fitzgerald Grady—which, so far as the police had been able to establish, was Dr. Ormond's real name. However, their association with the Institute of Insight would not be made public, and any proceedings would be carried out with the discretion that could be fully expected by blameless citizens of their status in the community.

They were fortunate, Cavender went on, in another respect. Probably none of them had been aware of just how much Grady had milked from the group chiefly through quiet private contributions and donations during the two years he was running the Institute. The sum came to better than two hundred thousand dollars. Grady naturally had wasted none of this in "research" and he was not a spendthrift in other ways. Cavender was, therefore, happy to say that around two thirds of this money was known to be still intact in various bank accounts, and that it would be restored eventually to the generous but misled donors.

Dr. Al's ex-students were beginning to look both chastened and very much relieved. Cavender briefly covered a few more points to eliminate remaining doubts. He touched on Grady's early record as a confidence man and blackmailer, mentioned the two terms he had spent in prison and the fact that for the last eighteen years he had confined himself to operations like the Institute of Insight where risks were less. The profits, if anything, had been higher because Grady had learned that it paid off, in the long run, to deal exclusively with wealthy citizens and he was endowed with the kind of personality needed to overcome the caution natural to that class. As for the unusual experiences about which some of them might be now thinking, these, Cavender concluded, should be considered in the light of the fact that Grady had made his living at one time as a stage magician and hypnotist, working effectively both with and without trained accomplices.

The lecture had gone over very well, as he'd known it would. The ex-students left for their homes, a subdued and shaken group, grateful for having been rescued from an evil man's toils. Even Mrs. Folsom, who had announced at one point that she believed she had a heart attack coming on, recovered sufficiently to thank Cavender and assure him that in future she would take her problems only to a reliable physician.
