Why does the French capital create such fascination? Because the City would not have Light if it weren’t for the contrast created by its shadowy areas. In the nooks and crannies legends are born... That of the Saint-Médard cemetry, home to the Convulsionnaires, that of the table of Good Humour which stands in the Paris Botanical Gardens without anybody really knowing how or why... Who knows of the Little Canon of the Palais-Royal or the unusual holiday destinations of Place de la Concorde? Together, we will wander the catacombs... Paris in fact owes a lot to the personality of its residents. From the flying Marquis to the mad baron of Saint-Cricq, the aristocrats capture our attention. And who exactly was Milord l'Arsouille? A guide which invites us to take an alternative look at Paris, one full of humour and originality.
