Black Panther - a one-of-a-kind emerald. When light shines on it from a certain angle, a black panther appears. Lupin, as per usual, acquires the gem and hides it temporarily in the museum in order to evade a body check by the strict security cordon, planning to come back for it later. But when both Zenigata and Inspector Conaiseau get involved as well, it's a real rough-and-tumble! What will become of the black panther?
