“Willey!  WILLEY!  Wait up!  I have an important delivery for you!” Someone was shouting at him.  It was Ivor Sack’Full, Trickletown’s postman, frantically peddling towards him, waving an orange envelope.  “Glad I caught you,” panted Ivor.  “This looks important.  I found it hiding in my sack whilst I was cleaning it out at the post office.”

Willey was pleased to see it, as it looked like the orange envelope that had delivered his mysterious circus ticket!

 “Thanks Ivor,”  said Willey.  “Auto Two, and make it snappy!”

Returning to the Key Stone, Willey slid his finger beneath the envelope’s sticky surface; he felt the paper ripple and, without any further help from Willey, the envelope revealed its contents.  A neatly written letter unfolded itself in his hands.
