Betty Murphy

The squad tries to solve a homicide case that is muddied by conflicting evidence, Maura must decide if she is going to take in her recently paroled grandfather, and Jane and Casey must decide between their careers and their relationship.

A pregnant woman researching her family history realises that her great-grandmother, Violet Holley, died in an unsolved murder. Rush tackles the 1929 case, her oldest to date, but she finds only a few notes revealing that underprivileged Violet had become pregnant by a wealthy man, Nick Bartleby. The recollections of those suspects who are still alive cannot be considered reliable, but Rush does locate Nick's great-grandson.
