On my right, there was a row of waterfront businesses – a fish market with a seafood restaurant above, a shop selling marine and fishing supplies, a commercial diving center, two yacht brokers. The building fronts are all weathered gray wood, with bright royal blue awnings that echo the blue canvas sail covers on boats all through the harbor. For a moment, I paused before a plate glass window, scanning the snapshots of boats for sale – catamarans, luxury cabin cruisers, sailboats designed to sleep six. There's a small population of "live-aboards" in the harbor-people who actually use their boats as a primary residence. The idea is mildly appealing to me, though I wonder about the reality of chemical toilets in the dead of night and showering in marina restrooms. I crossed the walk and leaned on the iron railing, looking out across the airy forest of bare boat masts.

The water itself was dark hunter green. Big rocks were submerged in the gloomy depths, looking like sunken ruins. Few fish were visible. I spotted two little crabs scuttling along the boulders at the water's edge, but for the most part, the shallows seemed cold and sterile, empty of sea life. A beer bottle rested on a shelf of sand and mud. Two harbor patrol boats were moored not far away.

I spotted a line of skiffs tied up at one of the docks below and my interest perked up. Four of the marinas are kept locked and can only be entered with a card key issued by the Harbor Master's Office, but this one was accessible to the public. I moved down the ramp for a closer look. There were maybe twenty-five small skiffs, wood and fiberglass, most of them eight to ten feet long. I had no way of knowing if one of these was the boat Daggett had taken, but this much seemed clear: if you cut the line on one of these boats, you'd have to row it out around the end of the dock and through the harbor. There was no current here and a boat left to drift would simply bump aimlessly against the pilings without going anyplace.

I went up the ramp again and turned left along the walkway until I reached Marina One. At the bottom of the ramp, I could see the chain-link fence and locked gate. I loitered on the walk, keeping an eye on passersby. Finally, a middle-aged man approached, his card key in one hand, a bag of groceries in the other. He was trim and muscular, tanned to the color of rawhide. He wore Bermuda shorts, Topsiders, and a loose cotton sweater, a mat of graying chest hairs visible in the V.

"Excuse me," I said. "Do you live down there?"

He paused, looking at me with curiosity. "Yes." His face was as lined as a crumpled brown grocery bag pressed into service again.
