This is an intriguing account of an underservedly little-known phenomenon, that of climbing the buildings of the 1930s University of Cambridge for sport and pleasure. Understandably done at night, to avoid the deserved attentions of the Proctors, the book chronicling it was also published pseudonymously, whilst the identities of those engaged in the practice were carefully concealed. However, the principle author is believed to have been Noel Howard Symington, who subsequently became involved in the British Fascist movement. The book is well written and is a fascinating piece of social history. ( )
