Long ago, the architect Stuart Pedrell told his family that he was going to the South Seas. However, his daughter Yes has recently received a postcard from her father that comes from a far less exotic place: L'Hospitalet. Carvalho goes to Bellvitge in order to find Yes' father and to discover why he lied to his family. Pedrell never went indeed to the South Seas. He took refuge in Bellvitge where he was murdered.
