Deadly Pride by Cynthia Hickey

The Seven Deadly Sins
One dedicated detective
A town in peril
Someone is making people pay for their sins and they’re targeting Detective Harper Scranton. When a wealthy resort owner is killed and a message left for Harper, it’s time to receive some help. She isn’t the only one receiving messages. So is FBI Special Agent Liam McConnell.
What they don’t know is that the man behind the messages has a diabolical reason for bringing the two of them together, and he won’t stop until he gets what he wants.
Can Harper and Liam stop a madman before he kills through the seven deadly sins or will they suffer for something they had no control over?
