I Spy with my Little Eye is a read and colour magazine story.
Percy and Daisy are playing "I Spy". Daisy says something beginning with "W" - Percy says "windows", but the Fat Controller says "work". Thomas and Henry soon join in, but the Fat Controller is worried there is not enough work, so he says "T" to Percy (for "trucks") and "P" to Daisy (for "passengers"). That evening, Thomas and Henry say "H" when they see the Fat Controller without his top hat.
