7 out of 10. You have to overcome incredulity toward the end. It is a beyond unlikely fortuitous witnessing of a near-crime. However, the story really engaged me, more so than most Conrad books. If you're considering Conrad for the first time, be aware that you'll have to deal with sentences like this: "In the full light of the room I saw in his eyes that slightly mocking expression with which he habitually covers up his sympathetic impulses of mirth and pity before the unreasonable complications the idealism of mankind puts into the simple but poignant problem of conduct on this earth." This sentence is quite complex and requires careful reading and analysis. Conrad's writing style is known for its depth and complexity, which can make his books a challenging but rewarding read. Despite the difficulty, the story in this particular book managed to draw me in and keep my attention throughout. The unlikely event at the end added an element of excitement and surprise, although it did stretch the boundaries of credibility. Overall, I would recommend this book to those who are willing to put in the effort to understand Conrad's writing and explore the themes he presents.
