Trivia

The telephone played an important role in The Edgar Wallace Mystery series. However, the standard British phone ring of the day comprised two steady rings with a cadence of 0.4 sec on, 0.2 sec off, 0.4 sec on, then 2 sec off. Presumably, to save time and inject a sense of urgency into the proceedings, British telephone rings in both this and many other presentations of the day were frequently speed-up, sometimes to twice the normal rate.

The title music "Man of Mystery" opened every episode, but the arrangements varied throughout the various series.

The alternative overall UK original television series version of the series of films title was "The Edgar Wallace Mysteries". The films were actually adaptations of all of the writings of author Edgar Wallace, originally released in cinemas as "supporting features" or B movies in the cinema chain division of the production company, later re-packaged as hour long tv episodes. So weren't officially a made for television filmed series, but were seemingly made with an eye on tv sales.

The features 'Crossroads to Crime' 'Urge to Kill' and 'Game for Three Losers' were not Edgar Wallace adaptations but were often later included to exploit the popularity of the series. ' Game for Three Losers' was originally an idea by Edgar Lustgarten for the 'Scales of Justice' series but because of its length became a second feature in its own right with its own title sequence.

Some television titles were called ' The Edgar Wallace Mystery Theatre' and in the tradition of TV only began with producer, director,writer and episode title , with the cast and technical credits left to the end captions. A lone guitar played on this one rather than the beat version.
