The Mystery of Mr. Wong (1939)

In the riveting sequel of the Mr. Wong series, Boris Karloff returns as the enigmatic detective entangled in a perilous web of treachery, theft and murder. The heart of the mystery is the 'Eye of the Daughter of the Moon', a captivating star sapphire of unparalleled size, stolen from the heart of China and smuggled into the United States. Its ominous allure stems from an ancient curse placed upon it by Emperor Hong Chong Tu, who buried it within his unfaithful wife’s heart. The intriguing tale unfolds as the gem falls into the hands of wealthy collector Brandon Edwards, a man all too aware of the impending doom that possession of the cursed sapphire might bring. Amidst a lavish party held within his opulent mansion, he confides his fears to Mr. Wong, revealing both the mesmerizing gem and a chilling death threat. Tragically, his foreboding proves true when, during a playful game of Charades, Edwards is mysteriously murdered, and the sapphire vanishes into the night. Unbeknownst to our astute detective, the jewel finds sanctuary in the hands of Edwards' loyal maid, Drina, who harbors a noble intention to return the gem to its homeland. Yet, the curse of the sapphire spares no one, leading to her tragic demise and the gem's subsequent disappearance. As the body count mounts and the suspect list dwindles, the mansion transforms into a haunting playground for deceit and murder. In the midst of the escalating chaos, a peculiar ensemble of characters emerge, from a peeking Chinese butler and a promising singer, to a competing criminologist, Richards' lawyer, and a suspiciously unsigned will. Together, they weave a complex tapestry of secrets and intrigue, which Mr. Wong must unravel. With his cunning intellect and steadfast resolve, Mr. Wong embarks on a quest to expose the ruthless killer and return the gem to its rightful place. As the tale reaches its thrilling climax, he hands over the unveiled murderer to Police Inspector Street, ready to embark on his next adventure. Immersed in a world of danger and deception, 'The Mystery of Mr. Wong' promises a classic whodunit that will keep you guessing until the very end.
