It's based on the William Kalush and Larry Sloman book The Secret Life of "Houdini", The Making of America's First Superhero. The tale paints Houdini as more than a master illusionist: He was a spy and a true renaissance man across the globe.
Sorry, no info about the next episode of Houdini (ABC) is available yet.
The TV show is either in vacation or waiting to start their new season. When information about future episodes becomes available, it will be posted here.
