"I'm Detective Roche," he then said, and he was oddly dressed in jeans and an old letter jacket. "I heard you say his hose was caught on something?"

"I did, and I'm wondering when you heard me say that."

I was on the pier now and not at all looking forward to carrying my dirty, wet gear back to my car.

"Of course, we monitored the recovery of the body." It was Green who spoke. "Detective Roche and I were listening inside the building."

I remembered Ki Soo's warning to me and I glanced at the platform below where he and Jerod were working on their own gear.

"The hose was snagged," I answered. "But I can't tell you when that happened. Maybe before his death, maybe after."

Roche didn't seem all that interested as he continued to stare at me in a manner that made me self-aware. He was very young and almost pretty, with delicate features, generous lips and short curly dark hair. But I did not like his eyes, and thought they were invasive and smug. I pulled off my hood and ran my fingers through my slippery hair, and he watched as I unzipped my wet suit and pulled the top of it down to my hips. The last layer was my dive skin, and water trapped between it and my flesh was chilling quickly. Soon I would be unbearably cold. Already, my fingernails were blue.

"One of the rescuers tells me his face looks really red," the captain said as I tied the wet suit's sleeves around my waist. "I'm wondering if that means anything."

"Cold livor," I replied.

He looked expectantly at me.

"Bodies exposed to the cold get bright pink," I said as I began to shiver.

"I see. So it doesn't-"

"No," I cut him off, because I was too uncomfortable to listen to them. "It doesn't necessarily mean anything".

Look, is there a ladies' room so I can get out of these wet things?" I cast about and saw nothing promising.

"Over there." Green pointed at a small trailer near the administration building. "Would you like Detective Roche to accompany you and show you where everything is?"
