There were fake diamond rings, all glass and paste and metal so cheap it took a week to get the green stain from your finger, and bottle caps for the three-shell game. There were cards with more marks than Omaha Beach on D-Day. And there were other, more elaborate cons too: papers heavy with official seals which promised the bearer the sun, the moon and the stars; lotteries that guaranteed the winner precisely zero percent of nothing; checks for ten or twenty different accounts, each with barely enough in them to keep them active but still sufficiently open to enable checks to be successfully written on them on a Friday night, giving them a whole two days of fiscal respectability before they bounced.

During the summer months, Saul Mann would trawl the resorts of the Maine coast looking for pigeons. He would arrive at Old Orchard Beach religiously on the third day of July, hire himself the cheapest room he could find, and work the beach for a week, maybe two at most, until his face started to become familiar. Then he would head up toward Bar Harbor and do the same, always moving, never staying too long, picking his marks carefully. And when he had amassed sufficient funds and the crowds began to peter away after Labor Day, when the trees slowly began to turn, Saul Mann would pack his bags and move to Florida to scam the winter tourists.

My grandfather didn't like him or, at least, he didn't trust him, and trust and like were the same thing in my grandfather's book. "He asks you to lend him a dollar, don't do it," he warned me, time and time again. "You'll get back ten cents if you get back anything at all."

But Saul never asked me for a thing. I met him first when I was doing summer work in the arcades at Old Orchard, taking money from little kids in exchange for soft toys whose eyes were held in place by half-inch-long pins and whose limbs were connected to the torso by the will of God. Saul Mann told me about the carny, about the joint scams: the basketball shoot with the overinflated ball and the too-small ring, the balloon darts with the soft balloons, the shooting gallery with the skewed sights on the rifles. I watched him work the crowds, and I learned as I watched. He targeted the elderly, the greedy, the desperate, the ones who were so uncertain of themselves that they would trust another man's judgment above their own. He sometimes went for the dumb ones, but he knew that the dumb ones could turn mean, or that maybe they wouldn't have enough cash to make the scam worthwhile, or that they might possess a low cunning that made them naturally distrustful.

Better still were the ones who thought they were smart, the ones who had good jobs in medium-sized towns, who believed that they could never be taken in by a grifter. They were the prime targets, and Saul relished them when they came. He died in 1994, in a retirement home in Florida, among the people he used to take as his marks, and he probably swindled them at canasta until the last breath left his body, until God reached down and showed him that, in the end, everybody is a mark.

Here is what Saul Mann told me.

Never give the suckers a break: they'll run if you do. Never have pity: pity is the mother of charity, and charity is giving money away, and a grifter never gives money away. And never force them to do anything, because the best scams of all are the ones where they choose to come to you.

Lay the bait, wait, and they will always come to you.

The snows came early that December to Greenville and Beaver Cove and Dark Hollow and the other central towns on the very rim of the great northern wilderness. The first flurries fell and people looked to the skies before hurrying on, a new quickness in their steps, spurred on by the cold they could already feel in their bones. Fires were lit, and children were wrapped up warm in bright red scarves and mittens colored like rainbows, and warnings were given about staying out late, about hurrying home before darkness fell, and stories were told in school yards about little children who had strayed from the path and were found cold and dead when the thaws came.

And in the woods, among the maples and birches and oaks, through the spruce and hemlock and white pine, something moved. It walked slowly and deliberately. It knew these woods, had known them for a long, long time. Every footfall was surely placed, every fallen tree anticipated, every ancient stone wall, long overtaken by the renewed forests and lost amid the undergrowth, was a place to rest, to draw breath, before moving on.

In the winter blackness, it moved with a new purpose. Something that had been lost had now been found again. Something unknown had been revealed, as if a veil had been drawn back by the hand of God. It passed by the derelict remains of an old farmhouse, its roof long collapsed, its walls now no more than a shelter for mice. It reached the crest of a hill and moved along its edge, the moon bright above it, the trees whispering in the darkness.

And it devoured the stars as it went.

It had been three months since I returned to Scarborough, following the death of the man who had taken my wife and child from me. I was back in the house where I had spent my teenage years after my father died, and that my grandfather had left to me in his will. In the East Village, where I lived for some time after my wife and child died, the old lady who owned my rent-controlled apartment had ushered me out with a smile on her face as she calculated the potential increase she could apply to the next tenant. She was a seventy-two-year-old Italian-American who had lost her husband in Korea, and she was usually about as friendly as a hungry rat. Angel suggested that her husband had probably handed himself over to the enemy to avoid being sent home to her again.

The Scarborough house was where my mother had been born and where my grandfather still lived at the time of my father's death, a widower alone but for his dog and his memories. Scarborough was changing when I arrived at the end of the seventies. Economic prosperity meant that it was becoming a satellite town for Portland and, although some of the older residents still held on to their land, land that had been in some families for generations, the developers were paying premium prices and more and more people were selling up. But Scarborough was still the kind of community where you knew your mailman and who his family was and he, in turn, knew the same about you.

From my grandfather's house on Spring Street, I could cycle north into Portland or south to Higgins Beach, Ferry Beach, Western Beach or Scarborough Beach itself, or down to the head at Prouts Neck to look out on Bluff Island and Stratton Island and the Atlantic Ocean.

Prouts Neck is a small point of land that protrudes into Saco Bay about twelve miles south of Portland itself. It was where the artist Winslow Homer set up house near the end of the nineteenth century. His family bought up most of the land on the Neck and Winslow vetted his prospective neighbors carefully since, by and large, he wanted to be left to his own devices. The folks out on the Neck are still that way. There's been a fancy yacht club there since 1926 and a private beach club with membership limited to those who live or rent summer homes in the area and who belong to the Prouts Neck Association. Scarborough Beach remains public and free and there's public access to Ferry Beach, close by the Black Point Inn on the Neck. Since it was beside Ferry Beach that Chester Nash, Paulie Block and six other men had lost their lives, the Neckers were going to have a lot to talk about when they returned in the summer.

In the old house, the past hung in the air like motes of dust waiting to be illuminated by the sharp rays of memory. It was there, surrounded by remembrances of a happier youth, that I hoped to set about putting old ghosts to rest: the ghosts of my wife and child, who had haunted me for so long but had maybe now achieved a kind of peace, a peace not yet mirrored in my own soul; of my father; of my mother, who had taken me away from the city in an effort to find solace for both of us; of Rachel, who now seemed lost to me; and of my grandfather, who had taught me about duty and humanity and the importance of making enemies of whom a man could be proud.
