Query: A huge achievement!

Ms. Smith's novel is a major work of crime fiction that goes way beyond the typical genre novel. Here you'll find deep characterization, a strong sense of place, powerful narrative drive and a compelling psycho-moral drama...qualities one finds only in the very best crime novels. Moreover, her heroine is a fascinatingly complex character. "Good Morning, Killer" is a huge achievement for this author, a fitting follow-up to her brilliant "North Of Montana" published a decade ago. Kudos to the author!
