Partners in Crime (Season 4, Episode 12)
It has been months since Jane took a vacation, and she's not about to miss this one, because her lover, Casey, is home from Afghanistan for a visit. She's eager to clear the decks at work so she can focus entirely on Casey, but two new back-to-back homicide cases spoil her plans.
The first victim is sociology professor Rhonda Clark, found dead in her hot tub. She just achieved tenure at BCU and had everything to live for until someone threw a radio in her tub, and then made sure she drowned by holding her head underwater. Why didn't her pet labradoodle bark? Did the dog know the killer? The obvious suspect is her husband, Rick, also a professor, but his alibi is rock solid. The only clue is a strand of dog hair found in Rhonda's lungs – and it doesn't belong to her labradoodle.
Meanwhile, in another part of town, arbitrage whiz Mark Cabot is gunned down in his healthclub parking garage. Since he was disliked by just about everyone, there's no shortage of enemies, including his own sister and wife. But both women can account for their movements. Once again, Jane is left with no obvious suspects – until a clue common to both murders raises the possibility the two deaths might be related.
While scrambling to work both cases, Jane is also trying to focus on Casey, who stuns her with an offer of marriage. If she says no, he'll stay in the military – and most likely return to Afghanistan. She loves him, but is that enough to keep them together?
Meanwhile, Maura has problems of her own. Her grandfather Paddy Doyle Sr. is being released after years in prison, and he's going to be living in her house. She soon finds out he's a vicious old man who despises her. Now she has to figure out how to get rid of her houseguest from hell – even if he is her grandfather.
