This time they are investigating the first death during a game of the Haden-centric sport of Hilketa. In Head On , the protagonist of Lock-In, famous Haden and FBI agent Chris Shane and his partner Agent Vann are back. John Scalzi’s 2014 science fiction/crime mash up Lock-In posited a world in which survivors of a worldwide flu epidemic were struck with what is called Haden’s syndrome, in which they have fully functioning brains in bodies that do not otherwise function. To counter this disability, neural interfaces have been developed that allow Haden sufferers to interact with each other in a virtual space called the Agora and to get around using either android bodies, known colloquially as ‘threeps’ (think C3-PO), or through specially wired humans known as Intefacers.
