Overview: The pie-throwing gun with which the head of the ECC personally supplies Zenigata is a special weapon: it immobilizes opponents with its adhesive pies. Fujiko and Lupin are arrested in rapid succession, but the ECC head's objective is unexpected. He forces them to solve the mystery of Napoleon's Fortune, by threatening them with guillotining in Tahiti. The clue is a single Elmeth scarf. Just as they solve it, they find their existences on the verge of death.
