The article starts from the assumption that Malcolm Lowry is fundamentally a one-book novelist. This is manifest in Lowry's compulsive going-back to his text, in what the authors designates as their obsessive repetitiveness. In the article this quality is illustrated by looking at the specific relation holding between the novels Under the Volcano and Dark as the Grave Wherein My Friend is Laid and by tracing this quality on the level of macrocomposition, characters and animal imagery in Under the Volcano. Finally, the author draws attention to the motif of the picture “Los Borrachones” as lending authority to his reading.
