The Key to the Lock

A book that's not supposed to exist pulls a man into a mysterious scavenger hunt with big prizes and bigger trouble. Is it just someone rich playing an elaborate game? It could be. Where the "game" will end he doesn't know, but the lure of money and adventure drives him forward from his mundane life, even after his life is put at risk. He'll find there's much more to this than a game, if he can keep ahead of those trying to kill him.
