Missing an 'E'

[randvjj]

I have been reading Oxford Reading Tree book 5c 'The Secret of the Sands' (with my two children) and you know how there is always something to find in each picture. In this book you have to find the letters to spell 'Treasure'. All three of us have hunted high and low to find the last 'E' but it is no where to be found - anyone on mumsnet found it?
I told my children I would find the answer! Please help.
Thank you

Hi

just gone and had a look in my sons book and its on page 22 in the treasure box is a yellow star kind of thing with a circle and in the circle is the letter E in white - it is difficult to spot !
