Betraying Trust in Bloomington, MN

Chief Sam Mason needs hard evidence to nail elusive drug dealer Lucas Thorne. Mayor Harley Dupont offers to provide it. But Dupont is murdered before he can talk.
Sam and Sergeant Jody Harris don't know who they can trust aside from their loyal K-9, Lucy. When the FBI comes sniffing around, their past actions come back to haunt them.
Just as Sam's strongest clue appears to be a dead end, a surprise twist reveals the truth behind Dupont's murder as well as the mysterious death of officer Tyler Richardson, and Sam learns that what he thought was a betrayal of trust was really something else entirely.
