Amidst the stark, lonely beauty of southwest Ireland's windswept coast, veterinarian Dimpna Wilde wrangles with dark traditions, village folklore, and a killer's motives during the annual Wren Day celebration in this deeply atmospheric and suspenseful County Kerry novel for readers of Dervla McTiernan, Lin Anderson, and Louise Penny.

Dingle is a town steeped in folklore, where old traditions like Wren Day linger like mist on the Kerry mountains. On the day after Christmas, St. Stephen's Day, the wren boys-local lads from competing neighborhoods-paint their faces and dress in straw garb to march through town. In times past, the tiny body of a wren would be displayed during the parade. According to legend, the little bird deserved to die for betraying St. Stephen's hiding place to his enemies.

These days, Wren Day is a kinder affair, with different groups vying to raise money for charity. But this year's celebration gets off to an ominous start when Dimpna finds a dead wren on her doorstep. Things take a darker turn when one of the wren boys is found strangled, thick fisherman rope still around his neck. Then Dimpna goes to return her friend Paul Byrne's dog to his house and discovers Paul dead-with a wren's body beside him.

Is someone sending a message that Paul was a traitor, or this an effort to cast suspicion on the wren boys? And how are the deaths connected? While Detective Sergeant Cormac O'Brien, visiting from Dublin, begins to investigate, Dimpna immerses herself in tangled motives that harken back to past tragedies, and a case that has become deeply personal. For it's not only traditions that persist here, grudges and secrets do too . . .
