The maids will put their lives on the line to expose the killer in the upcoming season finale of Lifetime's sexy hit series "Devious Maids."

In "Anatomy of a Murder," Hollywood Hills reports that Blanca's (Naya Rivera) murderer will finally be revealed. The maids will apparently take it upon themselves to unmask the killer, but in doing so, they are also risking their lives. In the past, Susan Lucci, who plays Genevieve in the series, hinted that all the clues were given for the viewers to figure it out.

In an interview with TV Line, the actress said that everyone in the cast was left guessing on who the killer was until the end. She also shared that when she finally found out, she was very surprised. Who could this mystery person be? Is he or she close to the maids?

Last episode, Rosie (Dania Ramirez) confronted Taylor (Brianna Brown) about the bloodstain on the couch. The latter, however, said that it was only wine, and that Blanca forgot to clean it up before she disappeared. When the maid told Marisol (Ana Ortiz) about what Taylor said, Marisol told her to spray the stain with hydrogen peroxide. She said that if it bubbled, then it was blood.

When Rosie went back to the Stappord home, she could no longer see where the furniture was. It turned out Taylor sold it, as she did not want her couch to have stains all over it. Marisol, however, was one step ahead of her. She managed to trace down the thrift shop were Taylor dumped the sofa. When they tested the peroxide on it, they found out that the stain was indeed blood. They now had solid proof that Taylor was somehow involved in Blanca's death.

As for the other women in the series, they each had a cross to bear. Evelyn (Rebecca Wisocky) was devastated that Deion's (Issac Ryan Brown) real father wanted the boy to come live with him. Genevieve (Susan Lucci) found out that Dr. Neff (John O'Hurley) set up Zoila (Judy Reyes) to get rid of her. Zoila, for her part, had to endure Gail Fleming's (Julie Claire) insults for her unborn child. Carmen (Roselyn Sanchez) went to Sebastian (Gilles Marini) to get comfort after a particular bad day of missing the baby that she gave up long ago.

"Devious Maids" airs Monday at 9 p.m. EST on Lifetime.
