Town Without Pity (6x18)

:

Frank and Danny work together to help Nick Constantine (Michael Nouri), a rehabilitated ex-con who Frank put away years ago, when Constantine becomes involved in the murder of an old enemy. Also, as Erin prepares for a murder trial, she learns the prosecutor who previously handled the case is withholding the location of the alleged killer so she can interview him on her popular podcast.
