Nick Harkaway’s new novel, Titanium Noir, continues in this vein. A mash-up of science fiction and hard-boiled detective story, it starts out promisingly enough. Cal Sounder, a “police consultant,” investigates the murder of a Titan, aged 90 but due to advances in technology inhabiting a 30-year-old’s body (and, when alive, standing more than seven feet tall). Cal’s investigation into this “dead nerd” spirals into unforeseen nooks and crannies, with dangerous repercussions.
