Mr Wolf's Birthday Surprise

If you liked the other Mr Wolf books, this is in a similar vein but, beware, it's much longer and denser than the previous titles and requires a fairly sophisticated reader of picture-clues to get the most from the surprise ending. For this reason it's more inclined to the upper end of the age-range. I think. The story of Mr Wolf's frustration and incomprehension, as all his friends refuse to play with him because they have parcels to deliver or are going out to tea, gave a great deal of pleasure to newly-independent readers, all of whom were very generous in explaining to me what the joke was!
