“Doctor, I am in a predicament. I will either have to invent some symptoms to account for my visit here, or make an excuse and bolt, or tell you what is bothering me, even though you will think I am a new sort of idiot.”

“Vincent, every day people invent symptoms to cover their visits here, and I know that they have lost their nerve about the real reason for coming. And every day people do make excuses and bolt. But experience tells me that I will get a larger fee if you tackle the third alternative. And, Vincent, there is no new sort of idiot.”

Vincent said, “It may not sound so silly if I tell it quickly. I awoke this morning to some very puzzling incidents. It seemed that time itself had stopped, or that the whole world had gone into super-slow motion. The water would neither flow nor boil, and fire would not heat food. The clocks, which I first believed had stopped, crept along at perhaps a minute an hour. The people I met in the streets appeared dead, frozen in lifelike attitudes. And it was only by watching them for a very long time that I perceived that they did indeed have motion. One car I saw creeping slower than the most backward snail, and a dead man at the wheel of it. I went to it, opened the door, and put on the brake. I realized after a time that the man was not dead. But he bent forward and broke his face on the steering wheel. It must have taken a full minute for his head to travel no more than ten inches, yet I was unable to prevent his hitting the wheel. I then did other bizarre things in a world that had died on its feet. I walked many miles through the city, and then I sat for hours in the park. I went to the office and let myself in. I accomplished work that must have taken me twenty hours. I then took a nap at my desk. When I awoke on the arrival of the others, it was six minutes to eight in the morning of the same day, today. Not two hours had passed from my rising, and time was back to normal. But the things that happened in that time that could never be compressed into two hours.”

“One question first, Vincent. Did you actually accomplish the work of many hours?”

“I did. It was done, and done in that time. It did not become undone on the return of time to normal.”

“A second question. Had you been worried about your work, about being behind?”

“Yes. Emphatically.”

“Then here is one explanation. You retired last night. But very shortly afterward you arose in a state of somnambulism. There are facets of sleepwalking which we do not at all understand. The time-out-of-focus interludes were parts of a walking dream of yours. You dressed and went to your office and worked all night. It is possible to do routine tasks in a somnambulistic state rapidly and even feverishly, with an intense concentration—to perform prodigies. You may have fallen into a normal sleep there when you had finished, or you may have been awakened directly from your somnambulistic trance on the arrival of your co-workers. There, that is a plausible and workable explanation. In the case of an apparently bizarre happening, it is always well to have a rational explanation to fall back on. They will usually satisfy a patient and put his mind at rest. But often they do not satisfy me.”

“Your explanation very nearly satisfies me, Dr. Mason, and it does put my mind considerably at rest. I am sure that in a short while I will be able to accept it completely. But why does it not satisfy you?”

“One reason is a man I treated early this morning. He had his face smashed, and he had seen—or almost seen—a ghost: a ghost of incredible swiftness that was more sensed than seen. The ghost opened the door of his car while it was going at full speed, jerked on the brake, and caused him to crack his head. This man was dazed and had a slight concussion. I have convinced him that he did not see any ghost at all, that he must have dozed at the wheel and run into something. As I say, I am harder to convince than my patients. But it may have been coincidence.”
