Translated from the back cover: "'Les Agences' ('The Agencies') presents the agents' daily life and unravels the rationale behind the most powerful agencies in the Twisted 50's, thanks to many organigrams and summaries. This sourcebook - destined to GMs - is packed with new rules - new occupations, new powers and duties per agency... - as well as with several game handouts which are essential to the staging of the general crackin-up that is spreading to the agencies."
