Much like Nabokov, Conrad didn't write in his native tongue ....
Conrad didn't even speak English until he was 21. I remember having to read Lord Jim in Freshman English many, many years ago. And like som of the people here, students were *****ing about the novel. There were a lot of Cs and Ds given in this course. But I stuck with it and now have read many of his novels, In fact, I have all his novels and stories in Folio Society editions. Conrad is hard to read at times, but the effort is worth it.
If your having trouble with Lord Jim, watch the movie with Peter O'Toole as
Jim and James Mason as Mr. Brown. It follows the book rather closely.
