In science one reasons by analogy, so when mankind is confronted by experiences entirely beyond its understanding it takes an individual with intelligence and bravery in equal measure to push back the boundaries of the unknown?In London, in the 1900s, the solutions to supernatural occurrences were investigated by a man who was famous for his dealings with the unknown and the worlds of the dead:

Jarrem Lee - Ghost Hunter, (or as he prefers to call it, a psychical detective). With the help of college student Arthur Bennett, he embarks on a series of spine-tingling and exciting adventures in the world of the dead.

Episode 21 - "The Suicides at Sevens Hall" - A terrible curse hangs over the Harkindale family causing each successive heir of Sevens Hall to commit suicide. When Jarrem Lee is contacted by the latest victim, he agrees to stay at the Hall and confront the dark spectre which haunts the family. Based on the story by E and H Heron.

Episode 22 - "The Fear Of Knowing" - Jarrem Lee is used to confronting ghosts, but when the spectra claims to be himself with a warning from the future, it complicates matters. Is this ghost to be believed, or is Lee but a pawn in a more intricate game?
