'Concrete Evidence': A skeleton is found in the concrete cellar floor of an old Edinburgh house. Whose skeleton is it? Was there a murder? Why? And who was the murderer? Is there any connection with the building company which laid the concrete floor thirty years before? Rebus has his suspicions, but before he can positively identify the dead man and his murderer, he needs 'concrete evidence'. 'The Gentlemen's Club': Seventeen-year-old Suzanne McKenzie was good at school, had rich parents and no boyfriend problems. So why should she kill herself? She was found naked in the bath with her wrists cut, even though — or perhaps because — she knew that her father would be the first to come into the bathroom that morning. The truths which Rebus discovers do not reflect well on the inner circle of Edinburgh society.
