This new edition of Conrad"s compelling tale of espionage and terrorism set in Edwardian London is based on a painstaking comparison of the original manuscript of the work with its first, truncated appearance, and with all subsequent book form publications overseen by Conrad himself. The result is this new text, purged of printers" errors and editorial interventions. Included are a critical introduction, an essay on the text itself, a textual apparatus, and helpul explanatory notes.
