Posthumous

Anna Corrigan, the daughter of the late movie star Mavis Edwards, has spent years trying to deal with the emotional fall out from the decades she spent with her often difficult and neurotic mother. Anna attends her sister Estelle's singing showcase at a tiny supper club, and encounters some of her mother's "friends" from the past: a crooked business manager named Louie Mayhew; old co-star Jerry Giddings, who has fallen on hard times; her rival Marjorie Easterbrook; choreographer "Busy" Borroway, an unrepentant child molester who numbered Mavis among his victims; and George Kelker, a director who refused to hire Mavis for an important production.
George is only the first of these individuals to be murdered by a crazed female intruder, who, Kelker's wife insists, looks just like Mavis Edwards! There had always been nutty stories in the tabloids about Mavis Edwards being alive and hidden in a sanitarium and with all these reports of a crazy lady who resembles her beginning to surface, Anna wonders if it could possibly be true. But as the murders continue and Anna finds her life unraveling, she learns that the truth is far more terrible than she could ever even imagine.
