"You're sweet, Zale," she said, pleased. Then, with a sigh, "But there's a lot more to it than that."

"You do all right that way too," he told her boldly.

She slapped the back of his hand and then, growing quickly serious, said, "Zale, I didn't ask you to meet me for that. I've got so much to ask you—so much to tell. Did you really find an assassin waiting for you when you got home last night? And did you kill him?"

"Yes and no," said Lindsay. "I did find one and I didn't kill him. In fact we parted good friends."

"You Martians...." She sighed, then said, "And I understand you have already broken two computers—this afternoon at the psychiatrist's and this evening at the Colosseum. It's the most marvelous news, darling. I've got to know how you did it."

"I'm damned if I know how I fouled up Dr. Craven's computer," he told her, "I'm still trying to figure it out."

Her face fell. She said, "I was hoping you had something.... But never mind." Then, brightening, "But you're driving them crazy. They ran Dr. Craven's results through Elsac late this afternoon and got the same answer. The records checked that you didn't kill your mother and I know you're not an invert." She laughed softly.

Spurred by the erotic atmosphere, plus the dizzying speed of recent events and Maria's nearness, he said, "Let's get out of here and go to my place."

Her hand covered his again atop the table. "I wish we could," she said wistfully. "I like you very much, Zale darling. But this is too important. We haven't time. But what about the tennis tonight? There's going to be an investigation, of course. Won't you tell me how you did it?"

"Not until I've figured out both," he said. "I may be on the track of something or it may be sheer chance. Until I understand what happened at Dr. Craven's I'm simply not sure of my facts."
