The Gongoozlers (S02E05)

Gavin Patterson is struggling with low ratings for his TV Garden Makeover show, prompting him to bring on Quinnie Dorell, a yacht enthusiast, as the new host. Unfortunately, Quinnie's gardening expertise leaves much to be desired, so she turns to Rosemary and Laura for assistance in presenting the episode. Things take a dark turn when Rosemary tumbles off a scaffolding in what appears to be a sabotage aimed at Quinnie. Shortly thereafter, the body of a young journalist, Rosie FitzCarron, is discovered in a remote lake, raising questions about the circumstances surrounding her death.
