Blood Staines - S2.E5

When a violent burglary occurs at Alex's in-laws' house, she comes face-to-face with their son Peter, the 14-year-old future father of Molly! Alex is desperate to help Molly's grandparents all she can, but Gene wants a big collar to bury the press stories of police corruption, and dismisses the case as trivial.

When the fingerprints from the crime scene reveal the burglar was George Staines, a notorious gangster, now supposedly dead, Gene realises this could be the catch he was after. Alex remembers hearing stories about the burglary, and is convinced that she would remember if the culprit was as infamous as Staines. Gene is determined to uncover the truth and get the headline he deserves.

Alex finally meets the mysterious man who has been leaving roses in her apartment and office. He tells her that she can go home to see her daughter again, but involves her becoming corrupt.
