First off, this is a pretty quick read - I read it on the way into work this morning, so less than an hour.
I'm not a Houdini expert by a long shot, but I know a little bit about the man, and find him interesting. This story starts with the basic facts about the man's life and weaves them into a moving fantasy piece that will keep you turning the pages. Fortunately - as I said - it's a short piece so you don't have to wait too long for the final reveal on Houdini's greatest trick that the world never knew about.
So: a quick read, a decent story, and 77p - what more do you want?
