She's dying, and she knows it. If only she can stay alive long enough to leave one last message. As the rain beats against the metal roof, she uses her blood-soaked fingertip to scrawl on the floorboards... The letters GB.

Detective Madison Knight has been house hunting, but a call from her real estate agent has nothing to do with finding the perfect property. She's found a woman's body, stabbed multiple times. Madison arrives on scene and is presented with an unknown Jane Doe and two letters written in blood. There's no murder weapon, and it seems Doe was attacked somewhere else.

As Madison works to find justice for the victim, Madison's own life is put at risk. What she comes to discover is some people will go to extreme lengths to protect their secrets-even as far as murder. But will learning that lesson come too late for her?
