It is the start of a long, hot summer and Madalena Grimaldi has disappeared. Claudia is hired to find the missing schoolgirl but she's already working on a case - the death of Guy Valentine, her father. As Claudia searches the streets, looking for the ghost of her derelict father and for the mysterious man who can lead her to Madalena, she finds herself sinking into a world where, for many, rock bottom is only the beginning.
