With Jane on edge with Casey's pending arrival, the team have two murders to solve. The first is that of sociology professor Rhonda Clark who was found dead in her hot tub. She appears to have drowned but only after someone failed in their attempt to electrocute her. The second death is that of 37 year old Mark Cabot, a member of an old Boston family who it appears was a ruthless businessman and disliked by virtually everyone who had dealings with him. The problem for the police is that anyone who might have wanted either one dead has a perfect alibi. A dog hair leads them to the solution. Meanwhile, Maura receives a letter from her biological father, Paddy Doyle, asking her to take his father - her grandfather - who is about to be released after 30 years in prison. As for Casey, he's facing a big decision - he's just made Colonel and has to decide if he will re-enlist, something he will do only if Jane refuses to marry him.
