At Clarence Colley's birthday party, the children play a game in which they hide, and then try to find the 10 shilling note Clarence has received as a present. Clever Clarence hides it in a neighbour's pocket, where none of the other children can find it, but realises he isn't quite so clever when Mr Duggan disappears from the party and Clarence finds out he's on his way to Melbourne for a business trip!
