Following an anonymous tip, Richard Moore travels to a remote inn to catch a murderer. Instead he finds evidence of river monsters. Conan is sure the killer is all too human, but then Rachel sees one of the legendary creatures for herself... Then Conan visits a hot spring where a movie crew's crime drama is interrupted by a real murder. And at a romantic chocolate-themed party, the host samples a not-so-sweet bite of cyanide. For older teen audiences.
