If you're a fan of Cain's prose these three short novels will satisfy. These are quite different from his more famous noir novels(Postman; Double Indemnity) but they still contain his unique brand of hard-boiled writing: minimalist sentences, crisp dialogue, and spare, economical description.
Serenade deals with an American opera singer (Cain trained as an opera singer before turning to journalism) who falls for a Mexican prostitute and brings her illegally back into the states where he begins a meteoric rise to fame, until something goes horribly wrong.
Love's Lovely Counterfeit is a tale of small town crime. A solid thriller.
The final novel, The Butterfly, is the most unique as it deals with the subject of incest in a West Virginia coal mining town. A nineteen year old girl shows up at a man's farm claiming to be his daughter, and takes things a little far with her sexual teasing. The plot takes several turns in its slim 90 pages, but I've never read another book quite like The Butterfly. The subject matter lends itself to Cain's spare, objective prose, because you need some distance from a topic like incest, and Cain hadles it well.
The book also contains a short preface to The Butterfly, where the author talks a bit about his biography and his approach to writing.
All three books are a solid 'B' grade, and fans of Cain, especially his writing style, should seek this book out.
