but that was
wrong. They had been retrogressed together and Dorn Starret had done
it; now he had come back to make certain that they didn't trace him.

Neat--but it wasn't going to work. Luis grinned wryly to himself. He
had a weapon in his pocket that was assurance it wouldn't work.

He got off the belt near the building he had seen Luise leaving
yesterday. He went into the lobby and located MEMORY LAB, a suite on
the top floor. It wasn't necessary, but he checked rental dates. The
lab had been there exactly three weeks. This tied in with Luise's
release from retro-therapy. Every connection he had anticipated was
there.

He rode up to the top floor. There wasn't a chance that Starret would
recognize him; physically he must have changed too much since the
criminal had last seen him. And while Luise hadn't concealed that she
was a retro and so had given herself away, he wasn't going to make
that mistake.

The sign on the door stood out as he came near and disappeared as he
went by. MEMORY LAB, that was all--no other name, even here.
Naturally. A false name would be occasion for police action. The right
one would evoke Luise's and his own memories.

He turned back and went into the waiting room. No robot receptionist.
He expected that; the man didn't intend to be around very long.

"Who's there?" The voice came from a speaker in the wall; the screen
beside it remained blank, though obviously the man was in the next
room. For a commercial establishment, the LAB was not considerate of
potential clients.

Luis smiled sourly and loosened the weapon in his pocket. "I saw your
advertisement," he said. No name; let him guess.

"I'm very busy. Can you come back tomorrow?"

Luis frowned. This was not according to plan. First, he didn't
recognize the voice, though the speaker could account for that if it
were intentionally distorted. Second, Luise was inside and he had to
protect her. He could break in, but he preferred that the man come
out.

He thought swiftly. "I'm Chals Putsyn, gallium importer," he called.
"Tomorrow I'll be away on business. Can you give me an appointment for
another time?"

There was a long silence. "Wait. I'll be out."

He'd _thought_ the mention of gallium would do it. True, the mine
Starret owned was probably worthless, but he couldn't restrain his
curiosity.

The door swung open and a man stepped out, closing the door before
Luis could see insi
