Once Trapped by Blake Pierce

In this dark psychological thriller, a wealthy husband turns up dead, and his abused wife is charged with the crime. She calls Riley for help—and yet it seems clear she is guilty.

But when another wealthy, abusive husband turns up dead, the FBI is called in, and FBI special agent Riley Paige wonders: is this all a coincidence? Or could this be the work of a serial killer?

What ensues is a game of cat and mouse, as Riley Paige realizes she is up against a brilliant and unpredictable killer, one without a clear motive—and one determined to keep on killing until he is caught.
