In gritty Glasgow, a police detective confronts criminals-as well as an enemy that lies within . . . In the seedy environs of 1980s Glasgow, Scotland, it takes guts to be a cop. DI Luc Kidston has guts-though he also has a weak spot thanks to his fear of heights. Now he must focus on finding a samurai sword-wielding vigilante-and untangling the case of one of his protégés, who's been arrested for allegedly putting a woman into a coma. Solving both problems will lead Kidston to take some unorthodox steps, including hiring a forensic hypnotist. It will also bring him into conflict with his own colleagues and lead him to fight for his life in a terrifying showdown . . .
