The hermit set out of camp at midnight, carrying his backpack and his bag of break-in tools, and threaded through the forest, rock to root to rock, every step memorized. Not a boot print left behind. It was cold and nearly moonless, a fine night for a raid, so he hiked about an hour to the Pine Tree summer camp, a few dozen cabins spread along the shoreline of North Pond in central Maine. With an expert twist of a screwdriver, he popped open a door of the dining hall and slipped inside, scanning the pantry shelves with his penlight.

Candy! Always good. Ten rolls of Smarties, stuffed in a pocket. Then, into his backpack, a bag of marshmallows, two tubs of ground coffee, some Humpty Dumpty potato chips. Burgers and bacon were in the locked freezer. On a previous raid at Pine Tree, he’d stolen a key to the walk-in, and now he used it to open the stainless-steel door. The key was attached to a plastic four-leaf-clover key chain, with one of the leaves partially broken off. A three-and-a-half-leaf clover.

He could’ve used a little more luck. Newly installed in the Pine Tree kitchen, hidden behind the ice machine, was a military-grade motion detector. The device remained silent in the kitchen but sounded an alarm in the home of Sergeant Terry Hughes, a game warden who’d become obsessed with catching the thief. Hughes lived a mile away. He raced to the camp in his pickup truck and sprinted to the rear of the dining hall. He peeked in a window.

And there he was. Probably. The person stealing food appeared entirely too clean, his face freshly shaved. He wore eyeglasses and a wool ski hat. Was this really the North Pond Hermit, a man who’d tormented the surrounding community for years—decades—yet the police still hadn’t learned his name?

Hughes used his cell phone, quietly, and asked the Maine State Police to alert trooper Diane Perkins-Vance, who had also been hunting the hermit. Before Perkins-Vance could get there, the burglar, his backpack full, started toward the exit. If the man stepped into the forest, Hughes understood, he might never be found again.

The burglar eased out of the dining hall, and Hughes used his left hand to blind the man with his flashlight; with his right he aimed his .357 square on his nose. "Get on the ground!" he bellowed.

The thief complied, no resistance, and lay facedown, candy spilling out of his pockets. It was one thirty in the morning on April 4, 2013. Perkins-Vance soon arrived, and the burglar was placed, handcuffed, in a plastic chair. The officers asked his name. He refused to answer. His skin was strangely pale; his glasses, with chunky plastic frames, were extremely outdated. But he wore a nice Columbia jacket, new Lands’ End blue jeans, and sturdy boots. The officers searched him, and no identification was located.

Hughes left the suspect alone with Perkins-Vance. She removed his handcuffs and gave him a bottle of water. And he started to speak. A little. When Perkins-Vance asked why he didn’t want to answer any questions, he said he was ashamed. He spoke haltingly, uncertainly; the connection between his mind and his mouth seemed to have atrophied from disuse. But over the next couple of hours, he gradually opened up.

His name, he revealed, was Christopher Thomas Knight. Born on December 7, 1965. He said he had no address, no vehicle, did not file a tax return, and did not receive mail. He said he lived in the woods.

"For how long?" wondered Perkins-Vance.
