In addition to Michael Dirda's Washington Post piece, three other reviews have surfaced in the last week or so:
Publishers Weekly: "This handsome, well-designed volume, with the Nelson interview revealing Macdonald's most personal thoughts and philosophy about a life spent writing, is an unmitigated triumph."
Kirkus Reviews: J. Kingston Pierce named It's All One Case as one of "Three Nonfiction Books Worth Adding to Your Library."
Mystery Scene: Kevin Burton Smith concludes: "Part serious bibliographical and biographical account, and part fanboy geek out, this is essential reading for anyone who ever looked for solutions to their own mysteries in a crime novel."
Plus, I have it on good authority that Tom Nolan's interview with me will appear in tomorrow's Los Angeles Review of Books.
