Ethan Beck is a gruff and surly homicide detective, new to the department after a rather forced transfer from Boston. Friends, boyfriend, who needs them? He's all about the job, and his cases are the only thing he needs to keep him warm at night. But all of that changes when he meets his new partner, Dr. Oliver Reagan. Oliver Reagan is the west coasts most renowned criminal psychologist. Getting into the minds of criminals and murderers is what he does best, not trying to figure out the inner workings of a certain homicide detective. So why does he find himself trying to figure out Ethan Beck? When the two of them are forced together, much to their chagrin, on a murder spree that rips through the streets of Portland, they must face their differences to catch the killer before they can strike again. Neither one of them is prepared for what is about to be discovered both in the case and between one another.
