April 2nd 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 in to living 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 gripping thriller and passionate love story.

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 — his 'grey wolves' — prey on the Atlantic convoys that are the country's only lifeline. Lieutenant Douglas Lindsay is amongst just a handful of men picked up when his ship is torpedoed. Unable to free himself from the memories of that night at sea, he becomes an interrogator with naval intelligence, questioning captured U-Boat crews. He is convinced the Germans have broken British naval codes, but he's a lone voice, a damaged outsider, and his superiors begin to wonder — can he really be trusted when so much is 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 the intelligence establishment. Lindsay decides to risk all in one last throw of the dice, setting a trap for his prize captive — and nemisis — U-Boat Commander Jurgen Mohr, the man who sent his ship to its doom...
