Cuts Like a Knife

Jane and Maura start putting together Jane's bed when they're called onto the case of a dead bride. Frankie seems to have a new interest in Jane's new neighbor, Riley. Frankie, Frost, and Korsak respond to a call of a person with a part of the cake that was missing from the crime scene. Frost and Korsak get Frankie to calm her down so they can get the knife away. When Jane and Maura walk into the Dirty Robber, they see Frankie and Riley on a date. Moments after Frankie leaves, Frost comes in and Riley begins a date with him. Later on, Leah has 'gone missing', which Jane and Korsak think that she may have been abducted. When Jane goes to ask Riley to help with her mattress she over hears her ordering liquid ecstasy on the phone. The next day Jane finds info on Riley, and Frankie goes in for his interview to become an inspector. While Maura is investigating the body she finds a branded 'k' on the victim's neck. Jane, Frost, and Korsak got to an old car company, where they found an advertisement in Leah's 'Wedding Album', only to find the building filled with women being sold. Frankie believes that he blew the interview, just when Jane goes to ask Cavanaugh if Frankie blew it, the drug team brings in Riley and the rest of her drug team. Cavanaugh tells Frankie that if he can't even read the woman he's dating, he's not fit to be a detective. Cavanaugh also criticizes Frost. Jane, Korsak, and Frost rush in to save Leah just before the killer was able to slit her throat.
