This is book number 8 in the Will Trent series.
“The Kept Woman features Georgia detective Will Trent in a compelling mystery involving a superstar sports figure, his wife, and a rape. The athlete had already been cleared of the rape allegations when a dead man is found in a building he is making into a high-end club with other wealthy investors. At the scene, blood is found that doesn't match that of the dead man, indicating that there is a second victim - a woman - in dire trouble. Another suspenseful tour de force from Slaughter.”
