This is not my Hat by Jon Klassen

A clever story for pre-schoolers and above, this has a moral lesson about the wrongdoing of steeling. A little fish steals a hat from a big fish, even though he knows it is wrong. However, he is sure he can escape the crime with a well-found hiding place. But is it good enough to avoid detection by the big fish? The dark restricted colour palette reflects the underwater sequence and the darker mood of this fishy tale. A quirky crime story with a difference.
