A large inheritance is up for grabs—and a murderer is on the loose—in the series that inspired the Netflix show Lupin. When a wealthy man named Cosmo Mornington dies, he leaves an immense inheritance to any living heir that can be found, and names his dear friend Don Luis Perenna as executor. But Mornington's heirs aren't easy to locate. By provision of the will, if none turn up after three months, the full sum of one hundred million francs will go to Perenna himself . . . otherwise known as master thief Arsène Lupin. While the French authorities have good reason not to trust Perenna, suspicion only escalates as Mornington's distant family members reach a series of untimely ends. But in a deadly race against time, there's no one better suited to catch a killer than the greatest thief in the world.
