1834 Time Travelling Teacher

Jason Slater is a very average twenty-first-century English teacher from Cheadle Hulme, but somehow wakes up after a few drinks in nineteenth-century Macclesfield. Apparently, he's now Tarquin, third son of Lord Belport, with a faithful valet, a suspicious brother, a spurned ex-girlfriend (who's now going out with his brother) - and no obvious way he'll ever get back home again.

From toasted sandwich makers and the perfect beer, to root canals and royal visits, can Jason - Tarquin, that is - change the course of history and make 1834 his playground? Or will all his modern sentiments and inventions cause total disaster for the rest of time - or at least the rest of his life)?
