Maurice Leblanc's classic 1906 thriller pits France's notorious Gentleman Burglar against England's Great Detective in a deadly duel over the legendary BLUE DIAMOND, stolen by Lupin with the help of the mysterious "Blonde Phantom" and which Holmes has sworn to recover at all costs. This new edition has been entirely retranslated for the first time since its original 1910 English publication. It also includes two new Lupin vs. Holmes short stories, Arsène Lupin Arrives Too Late and The Unkindest Cut (written by J.-M. & Randy Lofficier) and a complete chronology of all the Holmes-Lupin adventures.
