20/20 Edition - Headline 20th Anniversary Edition

The classic novel from the "master of our darkest dreams" and "a literary juggler"; The Times

They escape from a secret government: two mutant creatures, both changed utterly from the animals they once were.

And no one who encounters them will ever be the same again: a lonely widower; a ruthless assassin; a beautiful woman; a government agent.

Drawn together in a deadly hunt, all four are inexorably propelled towards an evil beyond human imagining.
