Meitantei Conan: Konjou no Fist

A valuable blue sapphire known as the "blue lapis fist," believed to have been lost on a pirate ship in the 19th century near Singapore, becomes the focus of a wealthy local's plan to recover it. When the gem is displayed at an exhibition in the Marina Sands hotel in Singapore, a murder occurs. A Kaitou Kid calling card, stained with blood, is discovered at the scene.
