Twisted — Jonathan Kellerman

With her energies focused on a baffling, vicious gang slaying and her personal life in shambles, Hollywood homicide detective Petra Connor has a full plate. The last thing she needs is a whiz-kid grad student claiming to have stumbled upon a bizarre connection between several unsolved murders. The victims had nothing in common, yet each died by the same method, on the same date--a date that's rapidly approaching again. And that leaves Petra with little time to unravel the twisted logic of a cunning predator who's evaded detection for years--and whose terrible hour is once more at hand.
