The poison tide - Andrew Williams

'You will be lucky if you come across a more engrossing and enjoyable historical thriller'

Allan Massie, Scotsman

1915. The British government faces its worst nightmare:

German guns on their way to Ireland and bloody stalemate on the Western Front. In London Sebastian Wolff is charged by the Secret Service Bureau with hunting down the enemy: a traitor reviled by the nation that hailed him as a hero, and a German-American doctor who is developing a terrifying new weapon that will change the face of war.

Wolff's spy mission will take him deep undercover into the corridors of power in Berlin, then across the Atlantic in a race against time to prevent catastrophe.

In total war there are no limits. But what about the human cost?
