Somewhere on the frontier between thought and reality exists the Discworld, a parallel time and place that might sound and smell very much like our own, but which looks completely different. Particularly as it’s carried though space on the back of a giant turtle (sex unknown). It plays by different rules. But then, some things are the same everywhere. The Disc’s very existence is about to be threatened by a strange new blight: the world’s first tourist, upon whose survival rests the peace and prosperity of the land.

Who would suspect that a gentleman of breeding could mastermind the daring theft of a fortune in gold? Who could predict the consequences of making the extraordinary robbery aboard the pride of England's industrial era, the mighty steam locomotive?

The fiction world of today needs a “Saint” more than it ever did. For years now that scene has been dominated by the “anti-heroes"—those grim gray operators in a sunless sub-culture where global issues are worked out with totally unemotional pragmatism, those hapless uninspired puppets manipulated and expended by ruthlessly dedicated little brothers of Big Brother. It made morbidly fascinating narrative, but it never gave anyone a lift until it climaxed in the hyper-gadgeted parodies of 007 extravaganzas.

She seeks answers from a member of the most prominent family of magicians, but she quickly learns that finding the truth won't be easy, especially when he turns out to be as artless as her, and more compelling and dangerous than books.

The only things he has really got going for him are the might of a thousand demons and his stalwart flatmate. Thankfully, Dr. Watson is always there to aid him through the treacherous shoals of Victorian propriety...

Penned by self-styled Most Amazing Man Who Ever Lived, Hugo Rune.
