The reader already knows from the title that a known character will be killed, which is a wide plot twist departure from most mysteries & crime novels. I didn't think I'd like the new pattern, but it works, as does the rest of the book, ending included.
The retail management plot & characters at the main character's workplace one hopes is satire, but despite its incredulousness, is an all too probable corporate environment.
I wouldn't say this is a riveting read, but maybe a study of narcissism in the human psyche & an alternative kind of justice. This book serves an interesting purpose: it explores the mind & motivation of a killer.
