The final volume of Cassegrain's "Trap on Zarkass!"
It's the final confrontation between the earthmen and the zarkassiens! For the human population of New Pondichery, besieged by the rebels, the evacuation is utter panic. Loulou and Marcel looking to escape the indigenous slums, disguise themselves wearing the mummified skins of two zarkassiens, and hoping to find a way onto a return shuttle. But Loulou is invaded by the spirit of the deceased zarkassien and joins the fight!
