Retired Department of Defense research analyst Lewis Cole loves his small New Hampshire town of Tyler Beach, and he shares this affection with his friend Jon Ericson, an eccentric retiree whoâ€™s convinced Vikings had once lived in their town, more than a thousand years ago. For years Ericson has searched for artifacts to prove Vikings had a settlement on the New Hampshire coastline, and when Lewis gets a phone message from Ericson that heâ€™s finally found this evidence, Lewis races over to congratulate him. But when he reaches Ericsonâ€™s house, however, there is no celebration: there is only a crime scene. In the minutes after the excited phone call, someone has brutally murdered Lewisâ€™ friend and stolen the artifacts. Who could have committed such a crime? Ericsonâ€™s estranged brother, a convict who deals in stolen antiques? A disgruntled town resident, jealous of Ericsonâ€™s quest? Or someone else who would easily kill to cover up such an archaeological discovery? These questions and others haunt Lewis, but Lewis is sure of one thing: he intends to avenge Ericsonâ€™s death, recover the missing Viking artifacts, and honor his friendâ€™s memory, even if it means paying a stiff price -- exchanging his beachfront home for a prison cell.
