Will the maids finally solve the murder mysteries in the finale episode of "Devious Maids" season 3? 

Based on the trailer for the upcoming episode titled "Anatomy of a Murder," the maids try to figure out who is responsible for the death of their new friend Blanca (Naya Rivera). However, all their lives will be put at risk in the process.

In the penultimate episode titled "Suspicion," Rosie (Dania Ramirez) finally learned the result of Marisol's (Ana Ortiz) investigation on the bloody sofa that Taylor (Briana Brown) asked her to get rid of. They learned that the blood belongs to Louie Becker, which could also be linked to Blanca's death. 

Will the girls' investigation lead to the arrest of the murderer that is currently walking freely in Beverly Hills? Does it also have something to do with Michael's (Brett Cullen) arrest? 

Meanwhile, another threat is looming over Adrian (Tom Irwin) and Evelyn's (Rebecca Wisocky) marriage, after Adrian's wrong move cost them the opportunity to legally adopt their foster son Deion (Isaac Ryan Brown). Evelyn threatened Adrian in the previous episode that she would divorce him if Deion's biological dad decides to take him away from them. When it came true, Evelyn becomes more determined than ever to end their marriage. 

But while Evelyn and Adrian are ending their marriage, Carmen (Roselyn Sanchez) and Sebastian (Gilles Marini) decide to level up their relationship by getting engaged. However, both couples' lives seem to be in danger when a mysterious figure enters with a gun, and it appears to be pointing at either the Powells or Carmen. Does it mean that there will be another death within the group? 

Viewers should also expect to see Zoila's (Judy Reyes) childbirth in this episode. 

The season 3 finale of "Devious Maids" is slated to air on Monday, Aug. 24, on Lifetime Network.
