Based on a series of books by French author Maurice Leblanc, this is the 4th mystery adventure game in Frogwares' Sherlock Holmes series.
Arsène Lupin is a French thief who arrives in London with one purpose - to steal 5 precious objects in the same amount of days from 5 distinguished locations, and get away clean. Will Lupin succeed in foiling Sherlock Holmes and Scotland Yard?
Help Sherlock discover when, where and how Lupin will strike by deciphering riddles and puzzles, talking with over 40 of London's citizens and finding important documents and objects. Dig for clues at many of London's famous sites - the British Museum, Buckingham Palace, the Tower of London and others. Review all of the material gathered in a journal as Sherlock races against the clock to catch Lupin. Play as both Sherlock and Dr. Watson intermittently during the game. It is played completely by mouse using a point-and-click interface.
