In the post-war mid-century Robert van Gulik produced a series of stories set in Imperial China and featuring a Chinese Judge: Judge Dee. This book examines the author's unprecedented effort in hybridising two heterogenous crime writing traditions - traditional Chinese gong'an (court-case) fiction and its Anglo-American counterpart - bringing to light how his fiction draws elements from these two traditions for plots, narrative features, visual images, and gender representation. Relying on research on various sources and literary traditions, it provides illumination of the historical contexts, centring on the cultural interaction and connectedness that occurred during the multidirectional global flows of the Judge Dee texts in both western and Chinese markets. This study contributes to current scholarship on crime fiction by questioning its predominantly Eurocentric focus and the divisive post-colonial approach often adopted in accessing works concerning foreign peoples and cultures.
