Lupin pulls off the heist before you even realize the setup is done, then spends the rest spinning jokes while everyone else is still looking at the map. The Napoleon Dictionary premise feels like it could collapse under its own contrivance, instead it becomes the excuse for perfect comic timing and a car race that actually matters. This is Lupin at his most purely fun, no mythology weight, just a thief who knows exactly how many steps ahead he needs to be.

Lupin the Third learns where his family's legendary treasure lies: the secret is written inside a dictionary that once belonged to Napoleon Bonaparte. When the book is offered as the prize in a classic car race from Madrid to Paris, Lupin sees his chance. He and his crew set out to win it or simply steal it, with the Inspector on their tail as always. They also face secret agents sent by the world's great powers, all chasing the key to the Treasure of the Empire. Vintage cars and cutting-edge weaponry keep this comic adventure special moving at speed.
