"What is your form of folly correction, Eldridge? How would you describe your profession?"

"I am," said Eldridge, "Associate Professor of Abnormal Psychology."

"Where do you…?" began Rubin.

Avalon interrupted, his deep voice dominating, "Sorry, Manny, but I smell an evasion. You asked Dr. Eldridge's profession and he gave you a title… What do you do Dr. Eldridge, to occupy your time most significantly?"

"I investigate parapsychological phenomena," said Eldridge.

"Oh, God," muttered Drake, and stubbed out his cigarette.

Eldridge said, "You disapprove of that, sir?" There was no sign of annoyance on his face. He turned to Henry and said, "No, thank you, Henry, I've had enough coffee," with perfect calmness.

Henry passed on to Rubin, who was holding his cup in the air as a signal of its emptiness.

"It's not a question of approval or disapproval," said Drake. "I think you're wasting your time."

"In what way?"

"You investigate telepathy, precognition, things like that?"

"Yes. And ghosts and spiritual phenomena, too."

"All right. Have you ever come across something you couldn't explain?"

"Explain in what way? I could explain a ghost by saying, 'Yes, that's a ghost.' I take it that's not what you mean."

Rubin broke in. "I hate to be on Drake's side right now, but he means to ask, as you well know, whether you have ever come across any phenomenon you could not explain by the accepted and prosaic laws of science."

"I have come across many such phenomena."

"That you could not explain?" asked Halsted.

"That I could not explain. There's not a month that passes but that something crosses my desk that I cannot explain," said Eldridge, nodding his head gently.

There was a short silence of palpable disapproval and then Avalon said, "Does that mean that you are a believer in these psychic phenomena?"

"If you mean: Do I think that events take place that violate the laws of physics? No! Do I think, however, that I know all there is to know about the laws of physics? Also, no. Do I think anyone knows all there is to know about the laws of physics? No, a third time."

"That's evasion," said Drake. "Do you have any evidence that telepathy exists, for instance, and that the laws of physics, as presently accepted, will have to be modified accordingly?"

"I am not ready to commit myself that far. I well know that in even the most circumstantial stories, there are honest mistakes, exaggerations, misinterpretations, outright hoaxes. And yet, even allowing for all that, I come across incidents I cannot quite bring myself to dismiss."

Eldridge shook his head and continued, "It's not easy, this job of mine. There are some incidents for which no conceivable run-of-the-mill explanation seems possible; where the evidence for something quite apart from the known rules by which the universe seems to run appears irrefutable. It would seem I must accept-and yet I hesitate. Can I labor under a hoax so cleverly manipulated, or an error so cleverly hidden, that I take for the gold of fact what is only the brass of nonsense? I can be fooled, as Rubin would point out."

Trumbull said, "Manny would say that you want to be fooled."

"Maybe I do. We all want dramatic things to be true. We want to be able to wish on a star, to have strange powers, to be irresistible to women-and would inwardly conspire to believe such things no matter how much we might lay claim to complete rationality."

"Not me," said Rubin flatly. "I've never kidded myself in my life."

"No?" Eldridge looked at him thoughtfully. "I take it then that you will refuse to believe in the actual existence of parapsychological phenomena under all circumstances?"

"I wouldn't say that," said Rubin, "but I'd need damned good evidence-better evidence than I've ever seen advanced."

"And how about the rest of you gentlemen?"

Drake said, "We're all rationalists. At least I don't know about Mario Gonzalo, but he's not here this session."

"You, too, Tom?"

Trumbull's lined face broke into a grim smile. "You've never convinced me with any of your tales before this, Voss. I don't think you can convince me now."

"I never told you tales that convinced me, Tom… But I have one now; something I've never told you and that no one really knows about outside my department. I can tell it to you all and if you can come up with an explanation that would require no change in the fundamental scientific view of the universe, I would be greatly relieved."

"A ghost story?" said Halsted.

"No, not a ghost story," said Eldridge. "It is merely a story that defies the principle of cause and effect, the very foundation stone on which all science is built. To put it another way, it defies the concept of the irreversible forward flow of time."

"Actually," said Rubin, at once, "it's quite possible, on the sub-atomic level, to consider time as flowing either-"

"Shut up, Manny," said Trumbull, "and let Voss talk."

Quietly, Henry had placed the brandy before each of the diners. Eldridge lifted his small glass absently and sniffed at it, then nodded to Henry, who returned a small, urbane smile.

"It's an odd thing," said Eldridge, "but so many of those who claim to have strange powers, or have it claimed for them, are young women of no particular education, no particular presence, no particular intelligence. It is as though the existence of a special talent has consumed what would otherwise be spread out among the more usual facets of the personality. Maybe it's just more noticeable in women.

"At any rate, I am speaking of someone I'll just call Mary for now. You understand I'm not using her real name. The woman is still under investigation and it would be fatal, from my point of view, to get any kind of pub-icity hounds on the track. You understand?"

Trumbull frowned severely. "Come on, Voss, you know I told you that nothing said here is ever repeated outside the confines of these walls. You needn't feel constrained."

"Accidents happen," said Eldridge equably. "At any rate, I'll return to Mary. Mary never completed grade school and has earned what money she could earn by serving behind a counter at the five-and-ten. She is not attractive and no one will sweep her away from the counter, which may be good, for she is useful there and serves well. You might not think so, since she cannot add correctly and is given to incapacitating headaches, during which she will sit in a back room and upset the other employees by muttering gibberish to herself in a baleful sort of way. Nevertheless, the store wouldn't dream of letting her go."

"Why not?" asked Rubin, clearly steeling himself to skepticism at every point.

"Because she spots shoplifters, who, as you know, can these days bleed a store to death through a thousand small cuts. It isn't that Mary is in any way shrewd or keen-eyed or unrelenting in pursuit. She just knows a shoplifter when he or she enters the store, even if she has never seen the person before, and even if she doesn't actually see the person come in.

"She followed them herself at first for brief intervals; then grew hysterical and began her muttering. The manager eventually tied the two things together-Mary's characteristic behavior and the shoplifting. He started to watch for one, then the other, and it didn't take long for him to find out that she never missed.

"Losses quickly dropped to virtually nothing in that particular five-and-ten despite the fact that the store is in a bad neighborhood. The manager, of course, received the credit. Probably, he deliberately kept the truth from being known lest anyone try to steal Mary from him.

"But then I think he grew afraid of it. Mary fingered a shoplifter who wasn't a shoplifter but who later was mixed up in a shooting incident. The manager had read about some of the work my department does, and he came to us. Eventually, he brought Mary to us.
