Ex-policeman Bernie Gunther thought he'd seen everything on the streets of 1930s Berlin - until he turned freelance and he is sucked further into the grisly excesses of Nazi subculture. The year is 1936 and Berlin is preparing for the Olympic Games. Some of Bernie's Jewish friends are beginning to realise that they should have left while they could, and Bernie himself has been hired by a wealthy industrialist to investigate two murders that reach high into the Nazi Party.

Bernie Gunther had his first brush with evil as a policeman in 1930s Berlin and came to know it intimately as a private eye under the Nazis, when each case drew him deeper into the enormities of the regime. Now the war is over and Gunther is in Vienna, trying to clear an old friend of the murder of an American officer. Amid decaying imperial splendour, he traces sprials of depravity that lead him to a former head of the Gestapo.

Munich in 1949 is a place where a private eye can find a lot of not-quite-reputable work. It fills Bernie Gunther with disgust - but it also fills his sorely depleted wallet. Then a woman seeks him out. Her husband has disappeared. She's not looking to get him back - he's a wanted man who ran one of the most vicious concentration camps in Poland. She just wants confirmation that he's dead.

Posing as an escaping Nazi war criminal, Bernie Gunther, Berlin's hardest-boiled private eye, arrives in Buenos Aires. When he reveals his real identity to the local chief of police, he discovers that his reputation as a detective goes before him. A young girl has been murdered in peculiarly gruesome circumstances that strongly resemble Bernie's final case as a homicide detective.

Berlin, 1934. The Nazis have been in power for just 18 months but already Germany has seen some unpleasant changes. Forced to resign as a homicide detective, Bernie is now house detective at the famous Adlon Hotel. The discovery of two bodies involves Bernie in the lives of two hotel guests. One is a beautiful journalist intent on persuading America to boycott the Berlin Olympiad; the other is a German-Jewish gangster who plans to use the Olympics to enrich himself.

It's 1954, and Bernie Gunther sails to Florida, where he's arrested, returned to Cuba, and imprisoned. There he meets Castro, and a French intelligence officer, Thibaud. Exhaustively questioned by Thibaud, Bernie is flown to Berlin with a proposition: work for the French or hang for murder. But Bernie's past as a German POW in Russia is about to catch up with him - in a way he could never have foreseen.

September 1941: Bernie Gunther's old boss, Reinhard Heydrich, orders him to Prague to stay at his country house. When a body is found in a room locked from the inside, the spotlight falls on Bernie to solve the mystery. If he fails to do so, he knows what is at stake - the reputation of Heydrich, a man who does not like to lose face. So begins the most diplomatically sensitive case of Bernie Gunther's police career.

In 1942,there are worse places to be than Zurich, and detective Bernie Gunther has seen his fair share of them. So when a superior asks him to track down a glamorous German actress believed to be hiding in Zurich, he takes the job. The actress, it emerges, is the daughter of a fanatical Croatian fascist, the sadistic commandant of a notorious concentration camp, and Bernie finds himself involved in something much more sinister.

Berlin, March 1943. The mood in Germany is bleak after their stunning defeat at Stalingrad. Private Investigator Bernie Gunther is at work in the German War Crimes Bureau - weary, cynical but well aware of the value of truth in a world where that's now a rarity. When human remains are found deep in the Katyn Forest, Bernie is sent to investigate. Rumour has it that this mass grave is full of Polish officers murdered by the Russians. For Josef Goebbels, proof of Russian involvement is sure to destroy the Western Alliance, giving Germany a chance to reverse its devastating losses.

It is 1956 on the French Riviera. A world-weary Bernie Gunther is working as concierge at the Grand Hotel, living under a false name. Then his past walks through the door in the shape of Harold Hennig, a former captain in the Nazi security service. Bernie never forgets a face, especially when it belongs to a mass murderer who, in 1945, was responsible for the deaths of thousands; among them a woman Bernie loved. Bernie has a score to settle with Hennig…

It's 1956 and Bernie Gunther is on the run. Ordered by Erich Mielke, deputy head of the East German Stasi, to murder Bernie's former lover by thallium poisoning, he finds his conscience is stronger than his desire not to be murdered in turn. Now he must stay one step ahead of Mielke's retribution. The man Mielke has sent to hunt him is an ex-Kripo colleague, and as Bernie pushes towards Germany he recalls their last case together, finding that there is some unfinished business awaiting him in Germany....

Autumn 1943. Hitler knows he cannot win the war: now he must find a way to make peace. FDR and Stalin are willing to negotiate; only Churchill refuses to listen. The upcoming Allied Tehran conference will be where the next steps - whatever they are - will be decided. Into this nest of double- and triple-dealing steps Willard Mayer, OSS agent and FDR's envoy to the conference. His job is to secure the peace that the USA and Hitler now crave. The stakes couldn't be higher.

America, 1960. In Washington, DC, John F. Kennedy has just been elected president. In Havana, Fidel Castro has been in office for a year, and with Cold War tensions rapidly heating up and the Soviets leading the space race, the thought of a Communist leader so close to home is already raising American blood pressure. Anti-Communist fever is rampant in the USA, with a paranoid establishment seeing reds under every bed. Nevertheless, the decision to snuff out the threat of Castro by hiring Tom Jefferson, America's best assassin, to kill him comes from an unusual quarter: the Mafia.

Belfast, 1988. A man is found dead, killed with a bolt from a crossbow in front of his house. This is no hunting accident. But uncovering who is responsible for the murder will take Detective Sean Duffy down his most dangerous road yet, a road that leads to a lonely clearing on a high bog where three masked gunmen will force Duffy to dig his own grave. Hunted by forces unknown, threatened by Internal Affairs, and with his relationship on the rocks, Duffy will need all his wits to get out of this investigation in one piece.

London rules might not be written down, but everyone knows rule one. Cover your arse. Regent's Park's First Desk, Claude Whelan, is learning this the hard way. Tasked with protecting a beleaguered prime minister, he's facing attack from all directions himself: from the showboating MP who orchestrated the Brexit vote and now has his sights set on Number 10; from the showboat's wife, a tabloid columnist, who's crucifying Whelan in print; and especially from his own deputy, Lady Di Taverner, who's alert for Claude's every stumble.
