The small police force of White Rock, New Hampshire, is still reeling from the death of Officer Tyler Richardson when they are called to the scene of the accidental drowning of an out-of-town camper.
But Chief Sam Mason and Sergeant Jody Harris soon discover the drowning was no accident. Someone murdered Lynn Palmer and staged the scene to make it look that way.
With a pool of suspects who aren't telling the truth and a corrupt mayor who wants the case solved yesterday, Sam and Jo follow a puzzling trail of clues with a surprise ending. And when a stray dog points them in the right direction, Sam discovers the killer is closer than he thought.
Just when Sam and Jo think they can rest after having solved Lynn's murder, a shocking discovery proves that sometimes even those you trust can be telling lies.
