At littlesville Primary School, the spinners belonging to year 5 had been mysteriously dumped in a tub of paint, put in the school shed and left to dry so they no longer spin.
But who put them there? Who sabotaged the spinners? A mixture of staff and pupils were in the frame.
Class 4 had to piece together the (maths) clues and solve the dastardly crime.
Did they solve the crime? Of course they did!
