In this tightly plotted yet mind-expanding debut novel, an unlikely detective, armed with only an umbrella and a singular handbook, must untangle a string of crimes committed in and through people's dreams. In an unnamed city always slick with rain, Charles Unwin is a humble file clerk working for a huge and imperious detective agency, and all he knows about solving mysteries comes from filing reports for the illustrious investigator Travis Sivart. When Sivart goes missing, and his supervisor turns up murdered, Unwin is suddenly promoted to detective, a rank for which he lacks both the skills and the stomach. His only guidance comes from his new assistant, who would be perfect if she weren't so sleepy, and from the pithy yet profound Manual of Detection. "The Manual of Detection" defies comparison; it is a brilliantly conceived, meticulously realised novel that will change what you think about how you think.
