The Mystery of the Red Tide Author:Frank Bonham Who is trying to get Tommy's uncle in trouble? Tommy and Jill look for the answer in the dark, forbidden tunnels by the ocean. Suddenly, their flashlight goes out! A frantic sound... and in the darkness, shining green footsteps appear on the floor of the cave...!
This is a wonderful book. It was one of my favorites as a kid, and I was so glad to find it again as an adult. The wonderful settings - old world war two tunnels, looking for sea creatures in the tide pools, even the light shining through a stained glass window into the fog, are all such fun to visit again.
