I'm sure that David Farrar could not conceive of later playing Sexton Blake in another film when as Granite Grant in Sexton Blake And The Hooded Terror he handed off a case to George Curzon as Sexton Blake in this story. I rather accepted Farrar better as a tough guy than I did Curzon.
Sexton Blake was a pulp fiction British detective who under various authors went for almost a century in adventures that entertained the British juvenile public. He's upper class like Sherlock Holmes, but more of a tough guy. In fact this thing is such a ripoff of Holmes stories it's ridiculous. He's got himself a housekeeper, a general factotum in Tony Gwynn, and he resides on Baker Street.
He's also got an arch nemesis called the Snake played here by Tod Slaughter who leads an army of criminals. Why Arthur Conan-Doyle didn't sue is beyond me. In any event the story takes place in London, Paris, and Cairo as Blake foils another dastardly plot.
Unlike Holmes, Blake gets a bit amorous in also helping French insurance detective Greta Gynt. Gwynn's character is not anything like Dr. Watson, he's more like Edward Brophy is to the Falcon.
One of those British quota quickies. Holmes fans might resent someone else moving on to Baker Street.
