Gumshoe is a new series of architectural books that introduces an original approach to the writing of architectural history. Emulating the detective novel, the focus is on actual buildings rather than on speculative designs and theories. The style and form are fresh and scholarly but also easy and enjoyable to read. In Mysteries of a Communist Cave, the second book in the Gumshoe series, Lytle Shaw conducts an investigation of Oscar Niemeyer's building for the French Communist Party's (PCF) central committee in Paris.
