When Granite Grant arrives at detective Blake Sexton's door on Baker Street, he has every intention of delivering news of the Black Quorum (the most powerful criminal organization of the century) and it's leader, the Hooded Terror. But he is garroted before Sexton's housekeeper, Mrs. Bardell, has time to answer the door. A clue on the body reveals the identity of the Hooded Terror to Sexton, who begins to pursue the Black Quorum, with the help of his faithful assistant Tinker and Mademoiselle Galley, a French secret service agent.
Yes, Sexton Blake outwardly bears some similarity to Sherlock Holmes such as being a genius detective, having a maid and living in Baker Street as well as having a sidekick, but character wise I didn't find Blake to be too similar with Sherlock as Sherlock tends to be more complex and up himself.
This is quite a fun B mystery thriller with a deliciously creepy performance by Tod Slaughter as the leader of the hooded terror, an odd and atmospheric sequence featuring dummies at the casino table, plenty of danger for our hero and a fast moving plot. Ok it's not as sharp as Basil Rathbone's Sherlock series and it can be a bit talky, but it's a decently entertaining film.
