As President of the Shoreham Detective Club, Pete Hollister called the meeting to order:

"You have all heard about the Shoreham monster. We're going to solve this mystery. But besides the monster, we have another project--the new toy library at the school. Pam will tell us about it."

His sister, Pam Hollister, rose: "It's a new kind of library--instead of borrowing books, children who can't afford toys can borrow them. I think the Shoreham Detective Club should help find toys for the library . . ."

Suddenly, the meeting was interrupted by a terrified scream. Holly Hollister stood pale and trembling, pointing to the window.

"I saw it I saw the monster It was wrinkled--like an old man--with big teeth "

And that is just the start of this newest adventure of the Happy Hollisters Before long, the Hollisters--and the other members of the Shoreham Detective Club--find themselves deep into a mystery that not only involves the "monster," but flying saucers . . . a mysterious airplane with an even more mysterious pilot . . . and the strangest case of kidnapping you've ever heard of
