DARK INTRUDER (1965) – This thoroughly enjoyable piece of Forgotten Television was a failed pilot for a series. Supposedly the network passed on it because they thought it was too scary and gruesome for tv viewers of the time. Instead they released this 59-minute black & white gem to theaters as the second title for double features.
The story is set in 1891 San Francisco with Leslie Nielsen himself starring as Brett Kingsford, an occult expert and investigator. If this had been picked up as a series the title was going to be The Black Cloak and apparently would have been a forerunner of The Norliss Tapes, Kolchak and Spectre. In my opinion the period setting would have given The Black Cloak the edge, though.
Brett Kingsford maintains a quasi-secret identity. On the surface he’s known in San Francisco as a bon vivant and ladies’ man and when the police want to consult him over something supernatural he dons various disguises to rendezvous with them. That way nobody in his usual social circles is made aware of his connections with the cops. Continue reading

Episode: FIVE HUNDRED CARATS (February 5th, 1973) 
For the first time in this series we have a story set outside Great Britain, which I found to be a welcome change of pace. Leo Lipinzki (Barry Keegan) works as a Detective Inspector for the Cape Police, but technically the already wealthy and powerful De Beers Diamond Corporation is who he really answers to.

Episode: THE MISSING WITNESS SENSATION (September 27th, 1971) 
The Missing Witness Sensation was an ideal choice to dramatize out of the more than two dozen Carrados stories. We viewers are treated to an excellent display of how every activity which sighted people take for granted is in itself a piece of detective work for blind Max. 
Episode: THE AFFAIR OF THE TORTOISE (November 22nd, 1971) 
In The Affair of the Tortoise Martin Hewitt is hired by Miss Chapman (Cyd Hayman), a former governess that he has just located so she could receive an inheritance from a distant relative. Miss Chapman wants Hewitt to clear one of her neighbors, Goujon (Timothy Bateson), of murder charges. 
Episode: THE HORSE OF THE INVISIBLE (October 18th, 1971) 
Given that this program is titled The Rivals of Sherlock Holmes the best way to describe The Horse of the Invisible would be as a hybrid of The Hound of the Baskervilles and The Speckled Band crossed with the John Silence series of occult mysteries. 
Episode: MADAME SARA (November 1st, 1971) 
Review: Years before the insidious Doctor Fu Manchu and his dogged adversary Sir Denis Nayland-Smith came this detective and the female criminal genius he clashed with. In the case of Dixon Druce and Madame Sara, there was always an air of attraction and sexual tension between them. 
As the episode opens, Druce is in his laboratory engaging in a game of forensic one-upmanship with his Scotland Yard friend Inspector Vandeleur (George Murcell). Their verbal fencing over poisons is interrupted by Dixon’s old school friend Jack Selby (William Corderoy). 
Their fortune of 2 million Pounds will be left to whichever of their children is ultimately left alive among Beatrice, her unmarried sister Edith (Caroline John of Doctor Who fame) and their elusive, enigmatic half-brother Henry Joachim Silva (THE Roger Delgado for another Doctor Who connection). 
Episode: THE RIPENING RUBIES (December 2nd, 1971) 
Bernard (Robert Lang) is capably assisted by Abel, the young clerk at his high-end jewelry shoppe. Abel is a reformed criminal whose old underworld contacts prove valuable in Sutton’s investigations.
