“What’s that?”

“On the California line near Topaz Lake there’s a state quarantine checking station. They check the cars that go through, particularly the cars that come into the state. They keep a record of license numbers… You went to Reno by plane?”

“Yes.”

“And stored your car?”

“Yes.”

“Where?”

“In a small garage where I sometimes keep it.”

“Do they know you?”

She smiled and said, “Not as Mrs. Tidings.”
