What happens

Lupin is shown a painting dated 15.4.2 by the narrator, who has observed that a neighbor, Louise d'Ernemont, leaves her home every April 15th. Lupin investigates and learns that the painting depicts a courtyard linked to a hidden treasure of the guillotined farmer-general d'Ernemont. He visits the notary Maître Valandier, who explains that three identical paintings exist, each held by different heirs, and that the treasure has never been found. Despite the notary's skepticism, Lupin deposits 5,000 francs to search for the treasure on the next April 15th, a year away.
