The Dain Curse contains Dashiell Hammett's typically marvelous writing style, complete with his superb characterization, atmosphere, and narrative technique. However, the novel suffers in that the actual plot is rather weak, and the flow of events is choppy. The book appears, at first glance, to be three loosely connected short stories involving the same characters. Although events from each sequence lead into the next, the progression of action is uneven because of the multiple climaxes that occur throughout the book. Additionally, the apparently tenuous links between the three sections of the novel are not at all ideal for maintaining the reader's interest. Events do finally come together in the last chapter, and Hammett explains how these seemingly disparate events tie together. Nevertheless, until that point the reader might well be wondering just what is going on.
If you enjoyed Hammett's other works, you will probably like this one. Casual or first-time readers, however, might very well find The Dain Curse to be off-putting.
