The Nightside is the dark heart of London - a dark, shady place, full of dark, shady characters, a corrupt place, where both dreams and nightmares come true, where anything can be bought for the right price, and where it is forever 3 a.m.

But to private detective John Taylor the Nightside is home, and he won't allow his home to be destroyed - even if he has to defeat his own mother to save it.

He is the only person able to stop her from exterminating the Nightside, a place that she created, but he fears that, whatever action he takes, the Nightside - and the rest of the world - will be doomed.

Nothing is ever simple.
