Scotland Yard sends Chief Inspector Dover and his assistant Detective Sergeant MacGregor to look into the murder of a local lad, Gary Marsh. Lord Crouch and his sister own Beltour, the stately home in whose grounds the body was found, and Dover was looking forward to their hospitality. Dover soon can't wait to finish the investigation - but chief suspects are numerous. His inertia, foul manner, and striking ineptitude are legendary - but there's work to be done, and as he says, 'I always get my man'.
