Even though seductive serial killer Gretchen Lowell is currently locked up in a mental institution, she still finds ways to manipulate police detective Archie Sheridan. Now she is having her shrink send urgent messages to Archie concerning a horrific murder case he's investigating.

At first, Archie refuses the calls, but when it becomes apparent Gretchen does know something that could help the case, Archie finds he must face this demon one more time. He finds a woman changed from what he remembers; the drugs she's on to control her are taking their toll on her beauty, as well as her health. Even though he doesn't want to believe the story she tells him, another murder has him taking the information seriously.

Chelsea Cain delves more into Gretchen's childhood background in KILL YOU TWICE, letting readers see more of why she's the way she is today. As always, the murderous chaos is sinister and significant involving the characters we've come to know well over the past four books in this series. The ending of KILL YOU TWICE begs for another book, so I'm sure we'll see more of Archie and Gretchen in the future -- here's hoping anyway.
