Charlie and his uncle Paton come to the old house where Charlie was once born. They find the house ransacked and Charlie notices two "not quite human" people running away. What did they want to find? Then a strange salty fog descends on the city, and a terrible howl is heard at night. Charlie and his friends must find the creature that howls so desperately. But will they make it? And what does Dagbert, the new boy with pale lips and cold aquamarine eyes, have to do with this? You will learn about this by reading this book.
