Olivier Schwartz creates an astonishingly beautiful Spirou adventure in an atomic clear-line style.

From the publisher:

Brussels, 1946. An unrelenting heat wave has swept the Belgian capital. On the rooftop, a leopard-woman flees, pursued by two giant robots, and finds refuge in the attic room of Colonel Van Praag, an irascible old coot. After Colonel Van Praag discovers the leopard, a young woman emerges. It is at this moment that in comes Spirou.

But Spirou is unrecognizable! Unable to forget the young Audrey (from a previous volume, Le groom vert-de-gris), our heroic bellhop has been drowning his problems in alcohol. The emergence of Aniota, the leopard-woman, shocks Spirou, and the strange creature takes him on a great African adventure in search of a charm stolen from her tribe! After a little detour to Saint-Germain-des-Prés, Spirou and Fantasio find themselves on the trail of Nazis!

This is one in a series of "one-shot" Spirou et Fantasio albums in which different writers and artists are allowed to tell a Spirou et Fantasio story set anywhere in the characters' timeline. This volume follows the events in "Le groom vert-de-gris" set in Nazi-occupied Brussels in 1942. 

 artwork is incredible.
