"Greener Grass" is the sixth episode of the third season of Blue Bloods.


When Erin's key witness is almost killed in a hit and run, she asks for Danny to be assigned as his protection. This proves vital as another attempt is made on his life soon after, so Danny must work to keep him safe and find the person behind the attacks.

Simultaneously he has to face with Linda's car trouble straining their already rough financial situation. Meanwhile, Jamie and Vinny end up making a drug bust while following a fake tip and get for clearance to find the woman who gave them the information to get the truth.

Elsewhere, Frank and Henry clash when Henry ends up in yet another fender bender. Frank tries to convince him to give up his car which Henry vehemently opposes.
