'Devious Maids' season 4 premiere spoilers: More relationship drama as Rosie comes closer to uncovering the truth

Ever since Peri Westmore was found dead in her mansion in Beverly Hills in the second episode of "Devious Maids" season 4, Rosie Falta had it in her to insist that her husband Spence Westmore, who was accused of the crime, is innocent. Now it looks like Rosie's hunches may be right!

In the previous episode titled "A Time to Spill," Rosie (Dania Ramirez) was inches from uncovering what actually transpired on the night Peri (Mariana Klaveno) was found with an award sticking out her neck. Apparently, the crime involved a few shifty Beverly Hills socialites.

Spence (Grant Show) has been accused of the murder of his ex-wife, and since he was too inebriated to remember the events of that evening, he surrendered to the police. Nevertheless, Rosie was insistent that Ben (Carlos Ponce) had something to do with Peri's death, and she was on target. She found out that Ben was drugging Spence to get him to confess to the crime, and that the drugs he used came from Kyle (Brian Hallisay), Ben's younger brother.

Rosie went to Genevieve (Susan Lucci) with the information she gathered, and it looks like "Mistresses" season 4 episode 6 titled "The Maid Who Knew Too Much" would see Rosie and Genevieve teaming up to prove Spence's innocence. However, if the synopsis for the upcoming episode is any indication, it looks like the sleuthing duo would be treading a dangerous path.

"Rosie seeks Genevieve's help with her investigation of Peri's murder, but things grow increasingly dangerous. Meanwhile, Marisol clashes with her director; Carmen poses as Danni at an audition; Kyle makes a difficult choice; and Evelyn dates someone new," said TV Guide's synopsis for the episode.

Meanwhile, Hollywood Hills said Marisol (Ana Ortiz) will continue butting heads with her new director, probably because of a "turning 40" joke while Carmen (Roselyn Sanchez) would apparently take advantage of her relationship with Daniela (Sol Rodriguez) while auditioning for a role. Oh, Kyle and Zoila (Judy Reyes) find themselves in a precarious situation, as Evelyn (Rebecca Wisocky) ends up dating someone new.

"Devious Maids" season 4 episode 6 will air on Monday, July 11, at 9 p.m. EST on Lifetime.
