After her entanglement in several homicide investigations, psychologist Natalie Marsh is determined to avoid further trouble. But when her intern needs help monitoring and calming family drama for the duration of a party, Natalie steps up. After all, acting as a peacemaker at a fundraising gala seems relatively risk-free in comparison to her past escapades—what could happen at a dance? When an argument between feuding guests becomes assault, Natalie realizes the situation is more complicated than she anticipated, with one man at the center of it all: Rowan Montrose.

Four years ago, Rowan’s brother was convicted of murdering his wife. But Rowan believes there’s more to the story, suspecting that the real murderer is walking free. His romantic interest in the younger sister of a police detective renders him more determined than ever to clear the family name. Familiar with Natalie’s reputation, he seeks out her assistance. Natalie tries to decline—she’s no private detective—but as frightening incidents unfold, it’s clear she’s in the middle of this whether she wants to be or not, and breaking through the layers of deception that hide the truth may have lethal consequences.
