The executor of the estate was Mornington's friend, Don Luis Perenna (AKA Arsene Lupin). The problem, however, was that no one knew where (or even who) some of the heirs were. If no heirs were to be found within 3 months, the entire $100 million francs would go to Perenna. And Perenna/Lupin had a reputation as being something of a rogue. It is definitely a race against time, as the heirs seem to be turning up dead at an alarming rate.
