1942: a German spy comes ashore on a desolate stretch of Lincolnshire beach. But he is hunted down by a young detective, Richard Prince. The secret services have need of a man like him.... In occupied Europe, Denmark is a hotbed of problems for British intelligence. Rumours of a war-ending weapon being developed by the Germans are rife. Sent to Copenhagen, Prince is soon caught in a deadly game of cat and mouse. Dodging Gestapo agents, SS muscle and the danger of betrayal, his survival - and the war effort - hangs in the balance. 

In the dying days of the Second World War, a group of Nazis frantically plot the next steps for their country. SS recruits gather east of Berlin to be trained for an audacious yet ill-fated mission to bring about a Fourth Reich. Three decades later, a young British diplomat in East Berlin is compromised after falling into a honey-trap. He contacts Major Edgar, a veteran British spymaster, now retired. Edgar is drawn into an unlikely alliance with an old adversary, Viktor, the veteran Russian spymaster.  

It's not unusual for spies to have secrets, but Henry Hunter has more than most, and after he is stopped by British Intelligence at Croydon airport on the eve of the Second World War, he finds he has even more. In March 1941 in Berlin, haunted by a dark episode from his past, he makes a fateful decision resulting in a dramatic journey to the Swiss frontier, with a shocking outcome.

France, July 1944: In the Pas de Calais, Nathalie Mercier, a young British special operations executive secret agent working with the French Resistance, disappears.

With the help of the Resistance, he finds Nathalie, but then the bitterness of war and its insatiable appetite for revenge catch up with them in a dramatic fashion.

February, 1944. A bitter winter grips occupied France, where Marc Reece leads a circuit of British agents risking their lives in order to sabotage the German war effort from within.

He must secure a document identifying a German spy at the heart of British intelligence. The fate of the Allied forces on D-Day is in his hands. 

Paris, 1943. The swastika flies from the top of the Eiffel Tower. Soldiers clad in field grey patrol the streets. Buildings have been renamed, books banned, art stolen and people disappeared. Amongst the missing is an Allied intelligence cell. Gone to ground? Betrayed? Dead? Britain's Special Operations Executive need to find out. They recruit ex-Parisian and Bletchley Park codebreaker Harry Mitchell to return to the city he fled two years ago. 

This is the incredible tale of Operation Fifth Column, a Second World War MI5 operation so secret that its existence was revealed by the National Archives for the first time only in 2014. Throughout the war and even for a couple of years afterwards, 'Agent Jack' - in reality, a bank clerk named Eric Roberts - acted as a Gestapo agent to whom hundreds of British-based Nazi sympathisers and informers passed their secrets, thinking that he was sending them back to Germany.

With the end of the Second World War in sight, the Allies begin to divide up the spoils, and it proves to be a dangerous game. The British have become aware that the Soviet Union is intent on controlling Austria once the war ends. Major Edgar is given the job of establishing an espionage unit in Vienna in order to track down Austria's most respected politician. But the feared Soviet spy Viktor Krasotkin is already embarking on exactly the same mission....

The upcoming Allied Tehran conference will be where the next steps - whatever they are - will be decided.

The stakes couldn't be higher.

A British officer has been murdered, and an RAMC signature is required for the post-mortem. Shocked by the identity of the victim, the bizarre nature of the crime and what appears a too-convenient resolution, Finch turns detective. He is soon thrust into a perilous maze of espionage and murder. 

Six weeks before she is due to take up her position as the first female head of MI6, Amelia Levene vanishes without a trace. Her disappearance is the gravest crisis MI6 has faced for more than a decade. There has been no ransom demand, no word from foreign intelligence services, and no hint of a defection. Should news of Levene’s disappearance leak out, the consequences would be catastrophic. But for disgraced MI6 officer Thomas Kell, the crisis offers a chance for redemption.

A Man Called Intrepid is the account of the world’s first integrated intelligence operation and of its master, William Stephenson. Codenamed INTREPID by Winston Churchill, Stephenson was charged with establishing and running a vast, worldwide intelligence network to challenge the terrifying force of Nazi Germany. Nothing less than the fate of Britain and the free world hung in the balance as INTREPID covertly set about stalling the Nazis by any means necessary.

September, 1940. The sun is shining, and in the midst of the good weather Londoners could be mistaken for forgetting their country was at war - until the familiar wail of the air-raid sirens heralds an enemy attack. The Blitz has started, and normal life has abruptly ended - but crime has not. That night a man's body is discovered in an unmarked van in the back streets of West Ham. When Detective Inspector John Jago is called to the scene, he recognises the victim: local justice of the peace Charles Villiers. The death looks suspicious, but then a German bomb obliterates all evidence.

London, 1963. The Beatles, Carnaby Street, mini skirts. But the new mood hasn't reached the drab and fearful corridors of MI5 and MI6. Many agents joined the secret service to fight the Nazis. Now they are locked in a Cold War against the Russians. And some of them are traitors. The service has been shaken to its core by the high-profile defections of Cambridge-educated spies Burgess, MacLean and now Philby. Appalled at such flagrant breaches of British security, the Americans are demanding a rigorous review.

On the brink of defeat, Hitler commissioned 10,000 V2s - ballistic rockets that carried a one-ton warhead at three times the speed of sound, which he believed would win the war. Dr Rudi Graf who, along with his friend Werner von Braun, had once dreamt of sending a rocket to the moon, now finds himself in November 1944 in a bleak seaside town in Occupied Holland, launching V2s against London. No one understands the volatile, deadly machine better than Graf, but his disillusionment with the war leads to him being investigated for sabotage.
