Rob Estes will join the cast on ABC's upcoming drama series Women's Murder Club, according to The Hollywood Reporter.

Women's Murder Club, from 20th Century Fox TV, centers on Lindsay Boxer (Angie Harmon), a homicide detective who solves tough murder cases with the help of her three girlfriends.

Estes will play Boxer's ex-husband, Tom, a politically savvy police lieutenant for whom she still has unresolved feelings. The role, which was small in the pilot, has been expanded.

Estes most recently recurred on CBS' CSI: Miami.
