I found this book after being disappointed by How to Write a Mystery by the Mystery Writers of America.

This is everything that wasn’t. Real, practical advice for writers with crime fiction as a focus. Exactly what it says on the tin.

If you’re a writer of any genre and of any level, I think there’s something for you in this book. This has good advice for beginners, but interestingly, that’s not all that’s in there.
There are some great musings on the writing life that will feel familiar to any writer.
