Case Files

A Victorian Mystery
A picnic treat has vanished, a trail of crumbs crosses the blanket, and every witness has a different story. Penny and Booger need sharp-eyed readers to compare the clues and name the cheese thief.

A haunted-hotel mystery
A light flickers inside the abandoned Hobart Hotel. Strange tracks, secret messages, and unlikely witnesses pull Penny and Booger into a case where every puzzle reveals another piece of the truth.


A jungle-temple mystery
Deep in the rainforest, a stone tarsier watches over a sealed temple. An inscription written in unknown symbols may open the way—if the detectives and their readers can crack it in time.


A pyramid-maze mystery
A mysterious map leads Penny and Booger through a twisting pyramid. A clue is found in the Mummy's tomb, but does it lead to the treasure or is it a curse?


An Old West mystery
The lost mine is full of false turns, abandoned tracks, and one dangerously short fuse. While searching for a missing miner, the detectives must follow the right trail before the final clue disappears in a flash.
