Season Finale. Episode Synopsis: Rizzoli & Isles Season 4 Episode 12 “Partners in Crime”- The squad rushes to solve a violent homicide case muddied by conflicting evidence. Maura is burdened with the major decision of whether to take in her recently paroled grandfather (guest star Richard Herd). Meanwhile, Jane and Casey (guest star Chris Vance) are forced to decide between their careers and their romantic relationship. Show Summary: Based on characters created by best-selling crime novelist Tess Gerritsen, Rizzoli & Isles stars Harmon as Jane Rizzoli, a tough-as-nails Boston police detective, and Alexander as Maura Isles, a smart, impeccably dressed medical examiner from a privileged background. Despite being complete opposites, the two women share an offbeat chemistry and strong working relationship that lets them solve complex murder mysteries in the city of Boston. As Rizzoli & Isles’ second season came to an end, a deep wedge was driven between the two friends when Jane shot Maura’s biological father, gangster Paddy Doyle (guest star John Doman). He had shown up unexpectedly at a secret undercover operation to protect Maura from a deadly assailant, but the scene quickly got out of control, forcing Jane to shoot Paddy. The aftermath strains Jane and Maura’s relationship as they try to understand and justify their reactions. When the third season opens, they are taken by surprise by an internal affairs investigation, pushing their friendship even closer to the breaking point. Ever the professionals, Jane and Maura will work hard to set aside their differences as they investigate a number of complex and troublesome crimes. Among their cases are the murder of a female graduate student, whose strangled body is found hidden in tunnels under her university; a killer with a bizarre doll fetish who hunts women on public transportation, then leaves their bodies posed on benches; and the stabbing of two young homeless veterans who survived Afghanistan only to be brutally murdered in an alley. On the home front, Jane’s meddling mother, Angela (Lorraine Bracco), is determined to play matchmaker. And Maura’s life gets more complicated as she searches for – and uncovers – the truth about her biological mother (guest star Sharon Lawrence). Rizzoli & Isles also stars Lee Thompson Young as Detective Barry Frost, Jane’s squeamish, computer-savvy partner; Bruce McGill as Sgt. Detective Vince Korsak, Jane’s steady old-school Homicide Squad teammate; Jordan Bridges as Jane’s brother, Frankie Jr., who dreams of becoming a detective like his sister; and Brian Goodman as Lt. Detective Sean Cavanaugh, the head of the Boston Police Detective department.
