A wealthy shut-in is found murdered in his mansion. Five other people were in the lavish home at the time of the crime?one of whom had motive enough to kill. And Detective Rachel Ryder is determined to discover who.

But the more she and partner Rob Bishop learn about the wealthy and unsociable victim, the harder it becomes to narrow down the suspect list. Frustrated, the investigators refuse to allow anyone to leave until the culprit is unmasked.

Now Rachel and Rob are sharing a roof with a cold blooded killer...and time is running out before the murderer strikes again.
