Snow is a rarity in Maura Donovan's small village in County Cork, Ireland, so she wasn't sure what to expect when a major snowstorm rolled in around Sullivan's pub. But now she's stranded in a bar full of patrons—and a suspected killer in a long-ago murder.

Maura's been in Ireland less than a year and hasn't heard about the decades-old unsolved crime that took place nearby, let alone the infamous suspect, Diane Caldwell. But the locals have, and they're not happy to be trapped with her. Diane, meanwhile, seeks to set the record straight, asserting her innocence after all this time. And since no one is going anywhere in the storm, Maura encourages Diane to share her side of the story, which she'd never had a chance to do in court.

Over the next few hours, the informal court in Sullivan's reviews the facts and theories about the case—and comes to some surprising conclusions. But is it enough to convince the police to take a new look at an old case?

A clever spin on the classic locked-room mystery, Cruel Winter, the fifth in New York Times bestselling author Sheila Connolly's series, will delight fans of the Emerald Isle.
