Silver Granger used to be a homicide detective. Now she's a private investigator working out of a cheap office in Riverview, taking whatever walks through the door. When grieving mother Lydia Morgan hires her to find the driver who killed her daughter Cynthia in a hit-and-run two years ago, Granger takes the case because it's the right thing to do and because the rent is due.

The police have nothing. Granger, through a mix of digital digging and old-fashioned legwork, traces the abandoned vehicle to a name: Tanya Thomas. The problem is there are two women by that name living in the city. One is a kindergarten teacher beloved by her community. The other is a queer activist with sharp edges and a complicated past.

Granger surveils both women, embedding herself in their lives to determine which one was behind the wheel. The investigation takes her from a violent confrontation in a Cleveland apartment to a one-night stand she never should have allowed. As the case tightens, Granger finds herself caught between two women who may be innocent, a client whose patience is running out, and an ex-lover on the force who warns her she's in over her head. By the time the truth surfaces, Granger will have lost more than the case.

Tell Me Who Did It is a queer noir novel about guilt, grief, and the distance between justice and vengeance. It is the first book in the Silver Granger series and introduces a protagonist whose greatest danger is not the cases she takes but the consequences she cannot take back.
