 Producers Nat Cohen and Stuart Levy acquired the rights to all of Edgar Wallace's books and stories in 1960.These were loose adaptations, very few using his original titles, and there was no attempt to set them in the period in which Wallace wrote, probably to eliminate the need for elaborate costumes and sets.A 1962 article in "Scene" magazine quotes £22,000 as the budget for an episode in production at the time of reporting.
