Spring 1941.  The armies of the Reich are masters of Europe.  Britain stands alone, dependent on her battered navy for survival, while Hitler’s submarines prey on the Atlantic convoys that are the country’s only lifeline. Lieutenant Douglas Lindsay is among just a handful of men rescued when his ship is torpedoed in the Atlantic.  Unable to free himself from the memories of that night and return to duty at sea, he becomes an interrogator with naval intelligence, questioning captured U-boat crews.  He is convinced that the Germans have broken British naval codes, but he’s a lone voice, a damaged outsider, and his superiors begin to wonder:  can he be trusted when so much at stake? As the blitz reduces Britain’s cities to rubble and losses at sea mount, Lindsay becomes increasingly isolated and desperate. No one will believe him, not even his lover, Mary Henderson, who works at the very heart of intelligence establishment. Lindsay decides to risk all in one last throw of the dice, setting a trap for his prize captive—and nemesis—U-boat commander, Jürgen Mohr, the man who helped to send his ship to the bottom

1915. German guns are on their way to Ireland. The British government faces its worst nightmare: insurrection at home while it struggles with bloody stalemate on the Western Front. A British spy, Sebastian Wolff of the new Secret Service Bureau, is given the task of hunting down its enemies: one a traitor reviled by the society that honoured him as a national hero; the other a German American doctor who, instead of healing the sick, is developing a terrifying new weapon that he will use in the country of his birth. Wolff’s mission will take him undercover into the corridors of power in Berlin — where he must win the confidence of the German spymaster who controls both men — then across the Atlantic in a race against time to prevent the destruction of the ships and supplies Britain so desperately needs to stave off defeat. Moving from London to the Baltic coast, from Berlin to New York, The Poison Tide is set against a war like none before, in which men die in their thousands every day. And there are those on both sides who will use any weapon, who accept no limits, no morality except victory

2 April 1879, St Petersburg. A shot rings out in Palace Square. The Tsar is unhurt, but badly shaken. Cossack guards tackle the would-be assassin to the ground. And in the melee no one notices a pretty, dark-haired young woman in a heavy coat walk purposefully away from the scene. Russia is alive with revolutionaries and this is just one of many assassination attempts on the unpopular Tsar Alexander II. For Dr Frederick Hadfield, part of the Anglo-Russian establishment with a medical practice dependent on the patronage of the nobility, politics is a distraction. But when he meets the passionate idealist Anna Petrovna, he finds himself drawn into a dangerous double life. Set in a world of stark contrasts, from glittering ballrooms to the cruel cells of the House of Preliminary Detention, from the grandeur of the British Embassy to the underground presses of the young revolutionaries, To Kill a Tsar is both a gripping thriller and a passionate love story
