Luis sat there a while longer, but he had recalled everything that would come out of the original stimulus. If he wanted more, he would have to dig up other facts or make further contacts. But at least it wasn't hopeless--even without the police, he had learned this much. He went over the room thoroughly once more. If there was anything hidden, he couldn't find it. He crossed the court to Luise's dwelling. She was gone, but there was a note on the table. He picked it up and read it: _Dear man with no name:_ _I suppose you were here last night, though I'm so mixed up I can't be sure; there's so little of memory or reality to base anything on. I wanted to talk to you before I left but I guess, like me, you're out investigating._ _There's always a danger that neither of us will like what we find. What if I'm married to another person and the same with you? Suppose ... but there are countless suppositions--these are the risks we take. It's intolerable not to know who I am, especially since the knowledge is so close. But of course you know that._ _Anyway I'll be out most of the day. I discovered a psychologist who specializes in restoring memory; you can see the possibilities in that. I went there yesterday and have an appointment again today. It's nice of him, considering that I have no money, but he says I'm more or less an experimental subject. I can't tell you when I'll be back but it won't be late._ _Luise._ He crumpled the note in his hand. Memory expert. Her psychologist was that--in reverse. Yesterday he had taken a day out of her life, and that was why Luise hadn't recognized him and might not a second time. * * * * * He leaned against the table. After a moment, he straightened out the note. A second reading didn't help. There it was, if he could make sense from it. Luise and himself, probably in that order. There was no proof, but it seemed likely that she had been retrogressed first, since she had been discovered first. There was also Dorn Starret, the criminal from Ceres who had hidden the gun in the Shelter that he, Luis, had been found in. And there was now a fourth person: the psychologist who specialized in depriving retrogression victims of what few memories they had left. Luis grimaced. Here was information which, if the police would act on it properly ... but it was no use, they wouldn't. Any solution which came out of this would have to arise out of his own efforts. He folded the note carefully. It would be handy to have if Luise came back and didn't know who he was. Meanwhile, the psychologist. Luise hadn't said who he was, but it shouldn't be difficult to locate him. He went to the screen and dialed the directory. There were many psychologists in it, but no name that was familiar. He pondered. The person who had retroed Luise and himself--what would he do? First he would take them as far from familiar scenes as he could. That tied in with the facts. Dorn Starret came from Ceres.
