When a group of men hire the master suite of Lily's and Robert's mansion, the brother and sister are looking forward to nothing other than the rent they'll receive. What they get is a dead body in a bath and another murder investigation. The victim is a hypocritical fire and brimstone preacher who made a practice of rape and sexual harassment. The list of people with motives gets longer by the day. Can Chief Walker solve the case or is this the case that'll break his perfect record?
