Love You Dead (Roy Grace #12), Peter James

Grace is newly married, having moved to a country cottage with Cleo and their baby son. But his first, long-missing wife, now found, has left Grace a surprise greater than he could have imagined.

Yet the police need Grace at work: an escaped murderer who left a bullet in him is back and a Black Widow is leaving an international trail of corpses after – in every sense – bleeding them dry. Now, she’s come to Brighton for her next rich target . . .
