Back in the Day

Frank's first partner Lenny Ross has decided to publish an expose book about their early days on the job. Garrett warns that the publicity of the book could both give Frank's enemies a weapon to use against him and harm his reputation, so he advises the P.C. to try to forcefully prevent the book from being published. This creates a rift between him and Ross, but after a talk with his family, Frank decides to be proud of the book's contents. Jack is being bullied at school, so Danny has him score revenge by dosing the bully's food with ipecac. Elsewhere, Jamie learns that Eddie got the two of them assigned to a stakeout for a home invader who might be visiting his mother. During the second night, a 10-13 comes in, but Eddie refuses to leave and he has to go on his own. Even though the call turns out to be no big deal and Eddie's stubbornness collars the crook, Jamie makes it clear that if she ever goes against an emergency call again, he will ask to get a new partner. Meanwhile, one of Erin's investigators is killed in a bar shooting. His best friend David tells them that he had been working a corruption case involving relief funds for Hurricane Sandy reconstruction contracts, but the case never made it to court because two witnesses were killed in mob-suspected hits. Later, surveillance reveals that David's father—an influential senator—orchestrated the hits because he was involved in the relief contracts, and his son ashamedly admits to slipping him the list of witnesses.
