an underrated addition to the graham greene cinematic canon it perceived fault can now be see a virtue . director shumlin and theatrical director and frame his action with an oppressive rigidity appropriate to the material and and the seemingly inept composition compellingly suggest unease . both a dark thriller and a story of moral regeneration ( for the female character . in a 40 thriller . ) and the film have an upright hero who turn mad and murderous ( and possibly paedophiliac ) and brilliantly bring the faraway ideology of the spanish civil war into jolt dangerous reality and have one horrific murder and an astonishing insight into class and capitalism and clever theatrical metaphor and a rare approximation of greene god and and an end that be only happy if you know nothing about history .
