Rent Midsomer Murders: Series 4: Who Killed Cock Robin? (2001)

Barnaby and Troy arrive in the village of Newton Magna to investigate the disappearance of a visiting horse whisperer. The man has been missing since he was hit by the local CP's car. The plot thickens, though, when Barnaby bumps into an old acquaintance, Melvyn Stockard. The detective chief inspector helped put Stockard in prison years earlier, but the ex-con insists he's now a reformed character. And the case is further complicated when a corpse is pulled from the village well. It's the body of local man Noel Wooliscroft - but who put him in there? And what does this have to do with the missing horse whisperer?
