Lupin doesn't need a heist premise to work, but this one finds one anyway: a dead professor, a missing manuscript page, and a granddaughter who has to decide whether to turn him in or trust him. The show treats the mystery like a locked room that gets solved mid-episode, then pivots hard into something stranger. By the end, you're watching Lupin be genuinely useful to someone who expected him to be useless, and that shift costs him nothing but changes everything about why you're rooting for him.

Lupin becomes the prime suspect in the killing of Professor Theo Argent, a scholar who had only just located a lost leaf from Marco Polo's famous chronicle of his journeys through the East. As the police hunt him down, Lupin gets help from someone he never expected: Lisa, the murdered professor's granddaughter. The special is a single-episode adventure with a strong comic streak, pairing a historical puzzle with Lupin's life on the run from the law.
