I read this book in about two hours. I don't think I can quite call it "amazing," as I reserve that rating for books that are a bit less ordinary, and this is, at the end of the day, a pretty ordinary mystery.
But it was a pacey, peppy read with a convoluted plot that sucked me right in and kept me going until the end. The solution relied on a technological world that no longer exists, but it was convincing for its time and entertaining as all get out. My favorite of this series so far!
I'll pick up Fugitive & Gumshoe sometime soon, as I'm thoroughly enjoying the series.
