Zone 22 by Tig Hague...

When Tig Hague kissed goodbye to his girlfriend Lucy, he was already thinking of his return. The couple were going house-hunting, looking for their first home together.

Tig was only going to be gone a few days on a routine business trip - the annual highlight of an otherwise unglamorous job working on the Russian desk of a London bank.

But just hours later something went wrong at Moscow airport. Very wrong.

Misunderstanding a request from customs for a backhander to speed his progress into the country, Tig was pulled to one side to have his bag searched. A deliberate inconvenience, he thought.

But Tig's world was about to implode with dizzying, terrifying speed.

A tiny lump of hashish, nothing more than detritus from a recent stag weekend, was discovered in the pocket of an old pair of jeans. Too small to warrant anything more than a slapped wrist back home, he hadn't even known it was there.

Tig was in Moscow's notorious Piet Centrale jail by nightfall - and that was just a stepping stone on his way to prison camp Zone 22 in the bleak, remote wastes of Mordovia.

He wouldn't be returning home for years ...
