Twice as Bright, Half as Long - Episode 15.01

For the first time in their long and illustrious partnership, Dave and Ian record together in the same room as they begin watching a new show: Randall and Hopkirk. In "Drop Dead," private detectives Jeff Randall and Marty Hopkirk are hired by an artist to protect his wife from herself, but when Marty is seemingly killed by her he comes back as a ghost, visible only to Jeff, in order to solve his own murder. In "Mental Apparition Disorder," Jeff is checked into a therapy center after telling Marty's finance, Jeanie, that Marty is a ghost. Meanwhile Marty is trained to be a ghost by the mysterious Mr. Wyvern. Finally, in "The Best Years of Your Death," Jeanie's nephew tells her something sinister is going on at his boarding school, so she and Jeff go undercover to discover the truth, and Wyvern teaches Marty possession. They make lots of Doctor Who connections, ask if Steven Berkov is locked in a cupboard, and Dave has an unfortunate chair incident.
