Another fun book in this series, and while I was afraid it could be the last, there's at least one more to look forward to, and maybe finally learn the entire story of Molly? I always love the Tolkien references, and with this book, Peter has finally, albeit grudgingly, graduated to the Silmarilion.
I read the whole thing, because I was hoping to find another copper story that I could sink my teeth into, but I'm probably not going to pick up the next book anyway. There's not enough suspense, the protagonists are certainly no Sherlock Holmes, and I did not care about the crimes they solved, of which there were too many.
I'm sure this would be a good introduction to fantasy for younger generations. My own younger self would have devoured these books, just like he couldn't get enough of Dianna Wynne Jones's children's fantasy. Adult me thinks it stretches a pretty straightforward story a little thin, but will still try to get a hold of the next part.
