Wolfgang Amadeus Mazart helps Inspector LeChat catch the thief who is stealing all the muffins of Europe.--This text refers to an out of print or unavailable edition of this title.
There is even a Municipal Bakery, where those unable to own ovens of their own (or the means with which to buy muffins) can bake their own, for a pittance. There a group of bakers opens the hot ovens, only to find the muffins gone! The muffin fiend steals from the poor as well!
Inspector LeChat and Mozart solve the mystery. Yes, one individual is stealing the muffins. No, he's not eating them.
Great Pinkwater-ish humor is on display throughout this book. The copy I read was 44 pages, half of which are illustrated. This was about a 20 minute read for me. It's probably perfect for children ages 6-10 who like silly humor.
Then again, i'm 33, and I liked it quite a bit.
