A father publicly beheaded. Killed in the blistering heat of a Saudi Arabian public square.

A young woman discovered. All of her identifying characteristics dissolved by acid.

A Syrian biotech expert found eyeless. Dumped in a Damascus junkyard.

Smouldering human remains. Abandoned on a remote mountainside in Afghanistan.

PILGRIM. The codename for a man who doesn't exist. A man who must return from obscurity. The only man who can uncover a flawless plot to commit an appalling crime against humanity.

'Simply one of the best suspense novels I've read in a long time.' David Baldacc
