The poor wretch Smallbone is close to the type of a canonical detective story: a murder has been committed—but who the culprit is remains unclear until the very end. The circle of suspects is limited, and many of them had both motives and opportunities to commit the crime. The narration is given special interest by the fact that the murder occurred in a law firm with a high, spotless reputation—telling about the firm’s activities, Gilbert feels like a fish in water.
