Mercy

the long version

"Police chief Cameron McDonald makes the toughest arrest of his life when his own cousin Jamie comes to him and confesses outright that he has killed his terminally ill wife out of mercy. As a heated murder trial plunges a small Massachusetts town into upheaval, Cameron--aiding the prosecutor's case against Jamie--is suddenly at odds with his devoted wife Allie, who sees Jamie's actions as not criminal but the ultimate act of selfless love. And when an inexplicable attraction leads to a shocking betrayal, Allie must search her own heart to find out what it means to truly love someone."--Back cover.
