It was Sam’s birthday so his grandmother baked him a cake to share with his classmates at lunchtime. Everyone was excited. All morning the children could smell the delicious chocolate cake. It made it very difficult to concentrate. Hohepa asked if they could have lunch early. Ling was caught ‘sniffing’ the cake. Ms Royal, the teacher decided everyone should go outside for a run before lunch. When they got back the cake was gone. All that was left were a few crumbs and a muddy footprint.

What can we find out about the cake thief to help narrow the search?
