This week's "Rizzoli & Isles" will see the dynamic duo of Jane Rizzoli (Angie Harmon) and Maura Isles (Sasha Alexander) investigating the death of a champion dog trainer who apparently fell victim to its prized show dog.

In this week's episode called, "Sister Sister," police investigator Rizzoli and medical examiner Dr. Isles will face a puzzling case in an apparent animal attack. A champion dog trainer was killed and it seemed that the primary suspect of the case is her own dog, a Rottweiler.

The woman was discovered dead at home alone with her dog and seemingly with no witnesses to the crime. The two partners have their work cut out for them if they are to find the real killer of the victim or if it's really the dog that is behind the vicious attack.

While the two worked on the case, it seems that Dr. Isles will have a little side story of her own.

According to the official synopsis posted on Carter Matt, "Maura has a peculiar interaction with Kent."

It is unclear at this point what kind of interaction or moment Dr. Isles will have with her new assistant, Kent (Adam Sinclair), but in an interview with The Hollywood Reporter in June, showrunner Jan Nash revealed that Kent's character was added because the production team "wanted to fill out Maura Isles' world, and have some more people who could be in her world, and we could see her as someone who manages people."

There seems to be no hint as to why the episode was called, "Sister Sister," but Fashion N Style speculated that perhaps it has something to do with the victim's family and murder. The suspect could be the dog trainer's sister or perhaps something else altogether.

Last week, Maura and Jane was caught in the baffling death of a college student hiker, who apparently fell to his death. However, the two saw that his fingers were broken and indicated that someone must have stomped on them as the victim hung on for dear life, which led to him falling to his death.

The two discovered that the victim had 32 girlfriends from the dating app, "Your Perfect Mate," and he was being paid to interact with women who signs up on the app to be their online boyfriend.

It turned out that the suspect is one of the victim's girlfriends who happens to be married. She decided to kill him after realizing that he did not love her and she became mentally unstable.

"Rizzoli & Isles" tenth episode, "Sister Sister," will air on August 18, 9 p.m. on TNT.
