She drew on her cigarette with a violence that caved in her cheeks. “They tried,” she said. “But I’m told it’s a wild, rugged country, hard to search. Nothing turned up. They couldn’t find a trace. They might have, if they’d looked very, very hard—made a mile-by-mile, hour-by-hour search. But they didn’t dare. You see, that particular milieu is critical. Mr. Gordon showed me the analysis. I couldn’t follow all those symbols, but he said it was a very dangerous century to tamper with.”

Everard closed one large hand on the bowl of his pipe. Its warmth was somehow comforting. Critical eras gave him the willies.

“I see,” he said. “They couldn’t search as thoroughly as they wanted, because it might disturb too many of the local yokels, which might make them act differently when the big crisis came. Uh-huh. But how about making inquiries in disguise, among the people?”

“Several Patrol experts did. They tried that for weeks, Persian time. And the natives never even gave them a hint. Those tribes are so wild and suspicious… maybe they feared our agents were spies from the Median king, I understand they didn’t like his rule… No. The Patrol couldn’t find a trace. And anyhow, there’s no reason to think the pattern was affected. They believe Keith was murdered and his scooter vanished somehow. And what difference—” Cynthia sprang to her feet. Suddenly she yelled—“What difference does one more skeleton in one more gully make?”

Everard rose too, she came into his arms and he let her have it out. For himself, he had never thought it would be this bad. He had stopped remembering her, except maybe ten times a day, but now she came to him and the forgetting would have to be done all over again.
