Big Fish Games today announced the release of Hidden Mysteries: Buckingham Palace, a hidden object casual game for the PC and Mac. The story begins when the Duke of Buckingham uncovers the long lost crown jewels. He is faced with two options, to declare that they have been discovered and risk a revolt by his people, or tuck them away safely in the palace for future generations to discover. The game will also be released through retail channels this November, but until then you can get it from their website. You might wish to check these screenshots first.
