This is probably the picture with the first portrayal of the famous sleuth that would have absolutely satisfied his 'creator', Arthur Conan Doyle. Arthur Wontner (who would play Holmes in four more movies) is exactly the eccentric, clever, cool and slightly sarcastic type that Doyle's 'Holmes' was in the novels - maybe even more exactly than Basil Rathbone, who would later become the most famous and 'characteristical' Holmes, playing the role no less than 15 times, because Wontner lacks Rathbone's haughtiness, which of course makes him more sympathetic to the audience... And the way he speaks in riddles, until the others actually think he's got some mental problem - although he's just giving them (and us) clues to the solution of the mystery - is also 'typically' Holmes; just like his favorite expression: "Elementary, my dear Watson, elementary!"
The VERY clever and twisted story is also treated in a masterful way and makes this movie, complete with the great acting of ALL involved and the moments of suspense and drama, but also of pure British humor, a REAL enjoyment for any fan of the crime genre or of classic movies in general; it's true that it doesn't have to show the scary special effects that the films with Rathbone had 10 years later - but it's a REAL treat for even the most demanding film fan to watch Holmes, obsessed with the idea that his arch-enemy, the criminal mastermind Moriarty, is behind all this, untangle the seemingly incoherent stories of card sharks and diplomats, real and forged money, boot makers and park trees; and maybe even be able to follow the master sleuth's thoughts and deductions!
One of the VERY best adaptations ever of a Sherlock Holmes adventure, this movie can easily compete with most of the - today much more famous - films starring Rathbone.
