Message in a bottle

When Harry Houdini comes to visit the seaside town of Sidford-on-Sea, Glory and her friend Dennis are first in-line to see him. He is there to perform a daring trick: he will jump off the town pier in chains, pitching himself into the water below. But when Glory outsmarts the infamous Houdini, she is suddenly sucked into his world, and finds herself tasked with looking after his precious trunk - the one that contains all his secrets. With Houdini in danger, Glory and Dennis are thrown deep into an adventure that takes them all the way to Coney Island in America, and the dark underbelly of its amusement parks.
