The police people paid no attention whatsoever to either my frantic arm-waving or shouts, not so much as a single person looking up to see what was going on in their reception area.

"Portia, they can't see or hear you. They can't see or hear any of us until the trial is over," Theo said, holding out a hand for me. "Walk over here and it will be over, and then I can explain to you what's going on."

"Dream on," I snapped, wondering if they'd drugged everyone in the police station. Maybe some sort of drug in the water cooler that made everyone unaware of what was going on around them?

"I'm afraid I'm going to have to put this down as a refusal," Terrin said, pulling a small notebook out of his pocket. "This will be the second trial you've failed, I believe. You know, of course, that if you fail a third you will be disqualified and your application denied?"

"What is it you want?" I asked Theo. "Money? You won't get it, you know. I don't have any, and Sarah's husband is a lawyer who would grind you under his heel if you so much as thought about holding her for ransom."

Theo dropped his hand. "Is the floor here?"

"Yes, of course it's here," I answered, avoiding looking directly at the abyss in front of me. I'm not afraid of heights per se, but they did make me a bit nervous. Even though I knew what I was seeing was an optical illusion, it was good enough to make my palms sweat.

"Then walk over here and prove that you believe what you are seeing is not real."

I licked my lips, looking from him, to Terrin, to the floor. It's not real, I told myself. It's just an illusion, a very high-tech illusion, but an illusion nonetheless. Things like floors do not just disappear into nothing. If I march over there now, I will be able to prove to both of them that whatever their nefarious plan is, it won't work on me. I will laugh in their faces.
