The second reason was the timing. I’d been told prank calls in the fall were unicorns, rare enough to be the stuff of legend. We were smack in the middle of October and the exodus was nearly complete. The majority of the seasonal residents, even the stragglers who tried to eke out a few more days of summer, had packed up their water trampolines and put their garish red-and-yellow cigarette boats in storage. The short-term tourists were back where they’d come from, too: Manhattan, Toronto, Montreal. This was the off-season in the Thousand Islands of upstate New York, nobody left but the locals. Just us.

Above all, though, I knew the call was legit because of the rain, sideways and lashing at that window by Tim’s desk. On the morning news the local weather guy—Bob? Ben?—said it was a nor’easter. The storm had started the previous day with lethal-looking green clouds that plunged the village of Alexandria Bay into premature darkness. It dumped freezing water on us all night and was expected to last forty-eight hours in all. Nobody wanted to be out in that weather, helping to dock a police boat. I couldn’t imagine anyone setting foot outside if they had a choice.

No, this call was the real deal. It was my first murder case in over a year, since the one that convinced me to trade Manhattan for total obscurity. I glanced around me. We weren’t the only investigators working out of our station, but we were the only ones present today, and now, somehow, I had to get to an island. “Grab your coat,” I said, watching Tim’s eyebrows inch upward. “We’re going for a ride.”

I used to think of boats differently, which is to say I rarely thought of them at all. A ferry to Ellis Island when my parents were in town and wanted to see the Statue of Liberty. A dinner cruise a few years back that ended with my date vomiting his shrimp cocktail into the East River. That was it for getting my sea legs. I hoped my inexperience wouldn’t be an issue today, but I knew it probably would.

It was a three-minute drive from the station to Keewaydin State Park, a straight shot up Route 12. I relished the warmth of the cruiser, savored the feel of my dry clothes while I had the chance. “What do we know?” I asked, flexing my fingers on the wheel. They were tucked into gloves I wished I’d thought to make toasty on the heaters before we left the station.

“That we’d rather be back inside with that coffee?”

I doled out half a smile. The coffee would’ve gurgled to the top of the pot by now. I could picture it steaming in the break room. By the time I saw it again, it would be cold, pungent sludge. “Besides that,” I said.

“White male age twenty-six, gone missing from a summer house. He was up from the city. It was the estate’s caretaker who called it in, noticed the guy’s absence first thing this morning.”
