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 features the writer Yann (Les Innommables) and artist Tarrin whose style is reminiscent of Conrad.
Nepal mountains, a mysterious rock-climbing expedition, Count Champignac, a castle, an uncovered crypt, a little living sphinx, and Spirou, Fantasio and the Count must solve the mystery of "The Ice Princess."
