"Three Bags Full" that's the name of the book I've read. I'm a mystery "cozy" kinda of reader and this was right up my alley. Now, I usually don't gush over things like this, but it was so charmingly written I just had to get the word out.
The "detectives" are sheep. Yeah, you heard me - sheep. They try and try to solve the mystery of why their shepherd is dead, but they are handicapped by their "sheepness" - it keeps getting in the way. So funny!
Check it out at the library.... even if you don't know anything about sheep, you'll never think about clouds the same way again, either.
