That Was No First Kiss

The squad investigates the death of a 99-year-old man who has been shot in the head sitting in his home. The case, which resembles a crime that happened in Tulsa three years ago, offers Grace and Perry an opportunity to utilize their expertise in gambling-related crimes from the vice days.   It also gives Bobby a chance to reconnect with his dad and Ham a chance to connect with a kindred spirit. But Grace's attention is drawn towards Rhetta when she learns something unexpected about Ronnie.
