I made a mental note to tell Mackenzie a few things about his pet controlled-environment tank—just as soon as I got out of it. I squinted at the over-face panel: air pressure, temperature, humidity, O-level, blood sugar, pulse and respiration—all okay. That was something. I flipped the intercom key and said, "Okay, Mackenzie, let's have the story. You've got problems...."

I had to stop to cough. The exertion made my temples pound.

"How long have you birds run this damned exercise?" I called. "I feel lousy. What's going on around here?"

No answer.

This was supposed to be the terminal test series. They couldn't all be out having coffee. The equipment had more bugs than a two-dollar hotel room. I slapped the emergency release lever. Mackenzie wouldn't like it, but to hell with it! From the way I felt, I'd been in the tank for a good long stretch this time—maybe a week or two. And I'd told Ginny it would be a three-dayer at the most. Mackenzie was a great technician, but he had no more human emotions than a used-car salesman. This time I'd tell him.

Relays were clicking, equipment was reacting, the tank cover sliding back. I sat up and swung my legs aside, shivering suddenly.

It was cold in the test chamber. I looked around at the dull gray walls, the data recording cabinets, the wooden desk where Mac sat by the hour re-running test profiles—

That was funny. The tape reels were empty and the red equipment light was off. I stood, feeling dizzy. Where was Mac? Where were Bonner and Day, and Mallon?

"Hey!" I called. I didn't even get a good echo.

Someone must have pushed the button to start my recovery cycle; where were they hiding now? I took a step, tripped over the cables trailing behind me. I unstrapped and pulled the harness off. The effort left me breathing hard. I opened one of the wall lockers; Banner's pressure suit hung limply from the rack beside a rag-festooned coat hanger. I looked in three more lockers. My clothes were missing—even my bathrobe. I also missed the usual bowl of hot soup, the happy faces of the techs, even Mac's sour puss. It was cold and silent and empty here—more like a morgue than a top priority research center.
