Fractured

Milwaukee homicide detective Ellie MacIntosh's bizarre case takes gruesome to a new level - and is eerily and frustratingly familiar. She has seen the signature work of the killer before, but cannot connect the victims. There isn't a single suspect in sight, but at least the case gives Ellie something to focus on instead of her chaotic personal life. Ellie's partner, Jason Santiago, is glad to be back on the job, even on a disturbing case like this one. Working with Ellie has evolved into a tangled relationship that is no longer platonic, at least to him. Jason's chance to make a move is now, but he's paralyzed by the fear he will ruin both his career and a partnership he values more than any he has ever had. When a timid woman named Rachel reveals that she suspects her promiscuous and charismatic roommate, Lea, has been involved in the grisly murders, therapist Dr. Georgia Lukens is put into the untenable position of deciding if these are the ramblings of a delusional patient or something more. As Ellie pieces together a macabre puzzle of past and present sins, it becomes clear that madness takes many forms and...it may be too late to stop her partner from becoming the next victim
