An exciting picture book, featuring brand new characters from highly-regarded, best-selling, multi-award-winning talent, Oliver Jeffers.

When life in the forest begins to change; when trees mysteriously lose their branches, when whole tree trunks start to disappear, when homes are lost, the only course of action for the forest dwellers is to begin a full scale investigation. Alibis must be proved, clues must be sought but even so, blame is never far from anyone's thoughts.

Who is the perpetrator of this heinous crime? Will justice be done?
