The starter's gun explodes and Hollis Grant excitedly begins her very first marathon race, only to stumble almost immediately over a body lying in the road, the body of the Rev. Paul
Robertson, her soon-to-be ex-husband. When the crush of runners passes and the medics arrive, it becomes clear that the Reverend has not collapsed from the rigors of the race, but has been
brutally stabbed. Although Hollis had emotionally distanced herself from her husband some time ago, her challenge now is to find out who, among his many detractors, would hate the Reverend
enough to stick a knife in his back. As Hollis and Detective Rhona Simpson probe the secretive life of Paul Robertson, they discover multiple motives for hatred and murder.
