A hiker found buried in a dune, a taciturn restaurateur lost at sea and a chef swallowed by mudslides ... and that Qwill thought spending a peaceful holiday in the cottage! Caught by a police investigation and of obligations to his "rank" Qwill will not know where to head! Besides that he has more than enough of these stories of little green men who obsess indigenous. Theater, libraries dedicated to extraterrestrial phenomena, investigates special sections, nothing is spared at the Cartesian everyone in Mooseville ... And yet, an amazing event will force him to ask the fateful question: what if ... Koko? The police investigation developed in this book is very interesting. Unfortunately it is quickly shipped to profit considerations less down-to-earth ... What Koko is extra-ordinary, that we knew. With 60 whiskers, the reason for his sensory gifts seemed justified. But to imply that the alien would Koko ... there, we fall into the grotesque! It's a shame, it just spoils the mystery that enveloped this cat since the beginning of the series. Hopefully it either where a false trail!
