While Conan tries to prove that a corpse found deep in the woods was the victim of more than just a hunting accident, the Junior Detective League gains a new member: a curious bear cub! Then Detective Moore's office is graced by a very traditional lady with very traditional - and very deadly - sword skills. And at a place called Mermaid Island, a woman is found hanged under a waterfall. It seems the legendary mermaid's curse has struck again... unless Conan and Harley Hartwell can find an all-too-human culprit!
