reading summary

i finished another chapter in my book called alfle bloom i am going to tell you about the chapter i read. Alfle woke up and heard a loud boom she thought it was nothing but it didn't stop so she tippy toed down stairs and she looked around to see what that noise was. She saw something move when she was down stairs and she screamed and quickly ran upstairs and she hid under her blanket .  I wonder what made all that noise.
