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!
