A peaceful day on the farm turns to panic when Hen discovers her egg has been stolen! The only one who can crack the case? Billiam Van Hoof, the world's number one goat detective (at least, that's what he calls himself). As Van Hoof questions the animals and collects clues--a piece of eggshell, a yellow feather, and some tiny footprints--the answer to the mystery becomes obvious to everyone except the bumbling inspector. Readers will enjoy piecing together the clues long before the hapless goat detective and will laugh along with his ridiculous conclusions.
