Road Runner by Michael Lilly
Remy and Todd are just getting comfortable when a series of death threats forces them to take refuge in a tiny town in New Mexico. Against his better judgment, an antsy Remy picks up detective work again and is thrust into a murder investigation. He quickly realizes these murders are no coincidence, and disturbing signs lead him to think they are connected to his unfinished business in Riverdell.
In the midst of yet another battle of wit, resources, mental fortitude, and emotional stamina, Remy is forced to confront the demons of his past and present. He can only hope he has what it takes to finish this once and for all.
