Mum's cross with me, said Jennifer.It's Mrs Green's fault, said Henry. But just who is Mrs Green? Henry knows that Mum is cross because Mr Moon has hooted at her; Mr Moon had been so impatient because he was fuming at being called 'stupid' by his wife; and his wife had been so irritable because she had been hurried in the supermarket - Like a line of cascading dominoes, there is a whole string of very recognisable scenarios to absorb before the identity of Mrs Green can be revealed. Who would have thought that her high heels tapping about in a flat above had started the whole chain of bad temper! Internationally acclaimed for his books about Elmer the patchwork elephant, this picture book has earned David McKee further popularity through its ebullient colour and wit.
