But that evening Peel managed to slip out with his binoculars. He walked along the quay, past the stranger’s darkened cottage and the oyster farm, and stood at the point where the creek fed into the Helford River, watching the sailboats coming in with the tide. He spotted a ketch heading in under power. He raised the binoculars to his eyes and studied the figure standing at the wheel.

The stranger had come back to Port Navas.

The ketch was old and badly in need of restoration, and the stranger cared for it with the same devotion he had shown his fickle MG. He toiled for several hours each day: sanding, varnishing, painting, polishing brass, changing lines and canvas. When the weather was warm he would strip to the waist. Peel couldn’t help but compare the stranger’s body with Derek’s. Derek was soft and flabby; the stranger was compact and very hard, the kind of man you would quickly regret picking a fight with. By the end of August his skin had turned nearly as dark as the varnish he was so meticulously applying to the deck of the ketch.

He would disappear aboard the boat for days at a time. Peel had no way to follow him. He could only imagine where the stranger was going. Down the Helford to the sea? Around the Lizard to St. Michael’s Mount or Penzance? Maybe around the cape to St. Ives.

Then Peel hit upon another possibility. Cornwall was famous for its pirates; indeed, the region still had its fair share of smugglers. Perhaps the stranger was running the ketch out to sea to meet cargo vessels and ferry contraband to shore.

The next time the stranger returned from one of his voyages, Peel stood a strict watch in his window, hoping to catch him in the act of removing contraband from the boat. But as he leaped from the prow of the ketch onto the quay, he had nothing in his hands but a canvas rucksack and plastic rubbish bag.

The stranger sailed for pleasure, not profit.
