After a spycam is discovered in a secure community, the homeowners association hires HEARTS to track down the culprit. Investigator Eva Thompson fits the description of every victim so far and volunteers to move into a vacant condo to draw out the suspect from within. But until they know what's behind the peeping, no one feels safe sending Eva as a decoy alone.

Joshua Simmons is Eva's ex and the one man she can't quite escape. As the county medical examiner, he frequently consults with HEARTS and cases—and uses that connection to keep close to the woman he's still not over. When Eva needs a fake husband to work alongside her as a decoy, Josh agrees on one condition: that Eva won't do anything to put herself in harm's way.

Living together stirs up old feelings and old passions. And while Eva and Joshua try to sort out their demons, a voyeur is on the loose and getting braver by the day.
