The minute he was out of sight, Reba dropped all pretense of touring and got down to business. I kept pace with her as she checked the names posted on the wall outside each office. When she reached Onni's, she shot a look down the hall to make sure Marty wasn't there. She moved to Onni's desk, grabbed a tissue from the box, and used it as she started opening drawers. "Keep a lookout, okay?"

I checked the corridor behind me. Searching is my all-time favorite sport (except for time spent with Cheney Phillips of late). The edgy thrill of invading someone's private space is heightened by the possibility of getting caught in the act. I wasn't sure what she was looking for or I'd have joined her in the game. As it was, somebody had to stand guard.

Still opening and shutting drawers, Reba said, "God, I can't believe Marty's so paranoid. Must be off his meds. Ah." She held up a chunky ring of keys that she jingled midair.

"You can't take those."

"Poo. Onni won't be in until Monday. I can put 'em back by then."

"Reba, don't. You're going to ruin everything."

"No, I won't. This is scientific research. I'm testing my hypothesis."

"What hypothesis?"

"I'll tell you later. Quit worrying."

She left Onni's office, trailing a hand along the wall as she returned to the reception area, scanning the lines of the ceiling. When she reached the elevators, she circled the central core, measuring with her eyes. Large abstract paintings dominated the walls and the lighting was such that one's attention was irresistibly drawn from one artwork to the next.

"It would help if I knew what you were looking for," I said.

"I know how his mind works. There's something here he doesn't want us to see. Let's try his office."

I wanted to protest but knew she wasn't listening.

Beck's corner location was prime – spacious, with clear cherry paneling and the same footstep-muffling green carpeting. The room was furnished with low-slung chrome-and-leather chairs of the sort that require winch and pulley action to remove yourself once you've been foolish enough to sit. His desktop was black slate, a curious surface unless he favored doing his long division in chalk along the length. Reba used the same tissue to avoid leaving latent prints on his desk drawers. I loitered uneasily in the doorway.

Dissatisfied, she pivoted. She studied every aspect of the room and finally crossed to the paneled wall, where she tapped her way across, listening for evidence of a hollow space behind. At one point, she activated a touch latch and a door sprang open, but the only treasure revealed was his liquor supply, complete with cut glass decanters and assorted glasses. She said, "Shit." She pushed the door shut and returned to his desk. She sat in his swivel chair and did a second survey from that vantage point.
