Goosebumps #22 Ghost Beach R.L. Stine First Scholastic Printing Paperback 1994

Jerry can't wait to explore the dark, spooky old cave he found down by the beach. Then the other kids tell him a story. A story about a ghost who is three hundred years old. A ghost who comes out when the moon is full. A ghost ... who lives deep inside the cave! Jerry knows that it's just another silly made-up ghost story.... Isn't it?
