Professor Scruffles and the Blueberry Bandit

Five mornings in a row, every blueberry muffin at the Sunrise Bakery has vanished. The back door locks itself. The spare key is gone. And the only clue is a tiny handprint in the flour.

Good thing Otis has a bow tie. When Dixie clips it on, her scruffy dog becomes Professor Scruffles, a detective with a brilliant nose and some truly terrible theories. Can they crack the case before breakfast?

The real Professor

Otis, before and after the bow tie.

Otis P. Scruffles is the real Chief Field Officer of Devin's Dogs. In the book, a tweed bow tie turns him into a detective. In real life, he mostly supervises from his chair.

Professor Scruffles and the Great Leash Heist

The Puddle Creek Dog Parade is in three days, and every leash in town has vanished. Red ones, blue ones, even Biscuit's sparkly bacon-print one. The Professor has a brand new bow tie, a very important nose, and absolutely no idea what is going on.

Dixie is going to need a bigger map.
