Once an international cat burglar, Rachel Blu has gone straight by establishing herself as a security investigator for major museums and jewelry stores. Her methods are extreme — she actually breaks into museums to check their security — but she is gaining a reputation as an excellent investigator.

Now the priceless Rousseau Ruby has been stolen in an impossible caper, and unfortunately Rachel is inadvertantly responsible. In a race across countries, dodging bullets, eluding her arch-enemy (and former lover), and rediscovering a lost love, she must locate the missing jewel before the police find her and put her away for good.
