A gentle, simple explanation of noises in the night. Nicky the kitten can't sleep because of all the noises, so he discovers what causes them one by one: the tree branch tapping on the window, the mouse nibbling in the cupboard, a tap dripping, etc. Intriguingly designed lift-the-flaps help the discoveries along, and Nicky is soon reassured. Good for the child who isn't really frightened but wants explanations.
