You hold in your hands a very sinister tale.

I have searched every nook and cranny to compile the evidence in Case File 13. Now, in this book, you will find the next eerie installment in the adventures of Nick, Carter, and Angelo, three monster-obsessed boys whose harmless trip to Mexico turned into something so horrendous, so revolting?

Wait a second, Mr. B! You're making this whole thing sound way scarier than it really was. Maybe dial it back a notch?

But Nick, it is that scary. In this volume alone there are haunted pyramids, alien artifacts, and even a mummy with a terrible curse.

True, but there's also the part with the hidden treasure, and the time when Carter used his knitting needles to?

Yes, all right, you win. Now, if you'll excuse me . . .

You hold in your hands a very sinister, VERY SILLY story, following the WACKY adventures of three boys whose expedition to Mexico turned into something OUT OF THIS WORLD. This is the fourth volume. Read on if you dare. . . .
