The Ghosts of Inverloch: Valerian & Laureline — Pierre Christin

Spatio-temporal agents must preserve Earth's future, always.
But is it still possible?

Galaxity's orders are rather bizarre, lately. Laureline has been left on stand-by in a Scottish castle. Valerian, haunted by recurrent nightmares, has been sent to capture a sentient being as if it were a wild animal -- an unsavoury task, to say the least. And on Earth in the 1980s, members of the military and political elites are descending into madness one by one. What future does our planet still have ... and who's so bent of changing it?

Two agents of 24th century Earth patrol space and time to safeguard both the planet's future and its past. The 11th volume of Valerian and Laureline, one of the most influential science-fiction comic series of the past 40 years!
