Unreasonable doubt : a Constable Molly Smith mystery / Vicki Delany.

Enhanced descriptions from Syndetics:

"Another brisk whodunit in a beautiful western Canadian setting with an appealing protagonist in Molly, whose personal life gets as much attention as her professional one." -- Booklist on the previous Constable Molly Smith mystery, Under Cold Stone .

What would it be like to return to your hometown after twenty-five years in prison for a crime you have maintained you did not commit? And why would you?

Walter Desmond is back in Trafalgar, British Columbia, having been officially exonerated when new evidence showed corruption at worst, incompetence at best, by the Trafalgar City Police conducting the investigation. His pitbull attorney is seeking five million in damages from the provincial government. But Walt has not returned to Trafalgar to pursue money or revenge. He just wants to know the why of it.

The family of the murdered girl, Sophia D'Angelo, is bitterly determined to see Walt returned to prison - or dead. But for Trafalgar's police, including Sergeant John Winters and Constable Molly Smith, the reality is: if Walter didn't kill Sophia, someone else did.

So, case reopened. It lands on Winters' desk. The records are moldering. One investigating officer is dead, the other is retired - and not talking. The police are instructed to treat Walt as if he'd never been arrested or convicted. Someone else apparently killed Sophia, someone still walking free.

But too many minds remain closed. It's good luck for Walt that a group of women in town for the dragon boat race are staying in the B&B where he's booked, women with no local prejudices. But then a townswoman, then a boat woman, are attacked by a rapist, the media gets active, and tempers dangerously flare.
