The Black Swan Killer

John Consequent is the world's only philosophical detective. He can't tell you whether your wife has been cheating or find the Maltese Falcon but if you need someone to convince you that your wife exists or find the true nature of consciousness, he's your man. So, when the police hire him to consult on a serial killer that is trying to prove that humanity is ultimately selfish, it's not his usual sort of case. To make matters worse, a group of nihilists are out to kill him for explaining the meaning of life to one of their buddies. John's going to need more than a clever argument and a comfy armchair to get out of this one.
