Dalziel and Pascoe - Season 2 Episode 3 Deadheads

Dick Elgood, an old fiend of Dalziel's, unofficially reports two strange, nearly fatal incidents and asks Dalziel to investigate. The subsequent investigation exposes a chain of bizarre, accidental deaths stretching back nearly three decades but not a single shred of evidence to suggest foul play! Each of the seemingly unconnected deaths have somehow or other benefited Patrick Alderman although it cannot be proven that he has any connection.
