"… If a detailed account of that silent contest could be written, it would take its place as the most brilliant bit of thrust-and-parry work in the history of detection." -Sherlock Holmes to Dr. Watson in Sir Arthur Conan Doyle's "The Final Problem". Professor Moriarty is almost ready to enact his nefarious plan! Sherlock Holmes suspects that something is about to happen, but he doesn’t know the details. As Moriarty's crimes set the final pieces into place, Holmes desperately searches London for the clues he needs to foil his nemesis. London's greatest intellects go head to head in this intense battle of wits! Holmes & Moriarty is an asymmetric two-player drafting game in which players take on these iconic roles. Over a series of hands, players try to win "cases" by drafting crimes and clues drawn from Conan Doyle's stories. Players mark their winning positions on the scenario board. If Moriarty can score three in a row, he can activate his master plan for the win! If Holmes can foil Moriarty's plans, he wins! —description from the publisher
