When Henry's compass disappears, dog detective Angus follows clues which lead him into danger and eventually to the thief, without Henry's ever knowing how his property was recovered.
I liked this book. The dog was detective and wanted to find the compass for Henry. Good that the dog didnt give up and kept looking for clues. Some of the vocabulary could be hard for kids and some might not know the words. The illustrations were black and white. Some were shaded and you can see lines in the illustrations.
