Ubisoft today announced that Secret of the Silver Earring, a crime-solving mystery adventure that puts the player in the tweed hat of none other than Sherlock Holmes, has shipped. The game invites players to explore 40 19th-century London locations as well as far-flung Brazil and India to search for clues and question witnesses to solve the murder of a wealthy tycoon. A promised 30 hours of gameplay means the quest will be far from elementary. Secret of the Silver Earring carries a rating of "T" for Teen and an SRP of $19.99.
