Billy Boyle

Two officers from the American troops stationed in Caserta, Italy, not far from Naples, have been found murdered. The MOs are completely different, and it seems like the officers had no connection to each other, but one frightening fact links the murders: each body was discovered with a single playing card: the Lieutenant, the 10 of hearts; the Captain, the jack of hearts. The message seems to be clear: If the murderer isn't apprehended, the higher ranks will be next.

Lieutenant Billy Boyle could have used a rest after his last case, but when his girlfriend, Diana Seaton, a British spy, goes missing in the Vatican, where she was working undercover, he insists on being assigned to a murder investigation there so he can try to help her.

March, 1944: US Army Lieutenant Billy Boyle, back in England after a dangerous mission in Italy, is due for a little R&R, and also a promotion. But the now-Captain Boyle doesn't get to kick back and enjoy his leisure time because two upsetting cases fall into his lap at once.

When an unidentified corpse washes ashore at Slapton Sandson England's southern coast, US army captain Billy Boyle and his partner, Lieutenant Piotr "Kaz" Kazimierz, are assigned to investigate. The Devonshirebeach is the home to Operation Tiger, the top-secret rehearsal for theapproaching D-day invasion of Normandy, and the area is restricted; no one seems to know where the corpse could have come from.

It's 1943: Amid the bitter, violent Solomon Islands campaign, Billy is assigned the murder investigation of a native coastwatcher whom future president Jack Kennedy discovered on a nearby island with his head bashed in. As the body count climbs, Billy must figure out whether Jack is a cold-blooded killer, even as war rages around him.

It's late May 1944. Captain Billy Boyle is court-martialed on spurious charges of black-market dealings. Stripped of his officer's rank, reduced to private, and sentenced to three months' hard labor, Boyle is given an opportunity: He can avoid his punishment if he goes behind enemy lines to rescue a high-value Allied soldier.

A murder in wartime Switzerland reveals Swiss complicity with the Nazis and profiteering during World War II. Billy and Kaz are sent to neutral Switzerland to investigate the murder of a Swiss banking official with ties to the Office of Strategic Services (OSS). Swiss banks are openly laundering gold "harvested" from concentration camps, and those that are profiting will do everything they can to protect their wealth and hide their dark secrets.

July, 1944, a full month after D-Day. Billy, Kaz, and Big Mike are assigned to investigate a double murder close to the front lines in Normandy. An American officer and a member of the French Resistance were found dead in a manor house outside the town of Trevieres. The investigation is shrouded in secrecy, due to the highly confidential nature of the American unit headquartered at the Manoir de Castilly; the 23rd Headquarters Special Troops. 

August, 1944: US Army detective Billy Boyle is assigned to track down a French traitor, code-named Atlantik, who is delivering classified Allied plans to German leaders in occupied Paris. The Resistance is also hot on his trail and out for blood, after Atlantik’s previous betrayals led to the death of many of their members. But the plans Atlantik carries were leaked on purpose, a ruse devised to obscure the Allied army’s real intentions to bypass Paris in a race to the German border. 

Just days after the Liberation of Paris, US Army Detective Billy Boyle and Lieutenant Kazimierz are brought to Saint Albans Convalescent Hospital in the English countryside. Kaz has been diagnosed with a heart condition, and Billy is dealing with emotional exhaustion and his recent methamphetamine abuse. Meanwhile, Billy's love, Diana Seaton, has been taken to Ravensbrück, the Nazi concentration camp for women, and Kaz's sister, Angelika, who he recently learned was alive and working with the Polish Underground, has also been captured and transported to the same camp.   

It’s September 1944, and the US is poised to launch Operation Frantic, a shuttle bombing mission to be conducted by American aircraft based in Great Britain, southern Italy, and three Soviet airfields in the Ukraine. Tensions are already high between the American and Russian allies when two intelligence agents - one Soviet, one American - are found dead at Poltava, one of the Ukrainian bases. Billy is brought in to investigate, and this time he's paired, at the insistence of the Soviets, with a KGB agent who has his own political and personal agenda. 

Southern France, 1944: What should be a simple assignment with a Special Operations Executive officer gets complicated quickly as Billy navigates the tensions between Resistance groups in the process of gathering information on Vichy officials and other collaborators who escaped with the retreating Germans. Unexpectedly, the SOE officer has many enemies in the Resistance, linked to the failed Vercors uprising. With sacrifice and betrayal afoot, Billy doesn’t know who he can trust, or how close to death this case may bring him.

Norfolk, England, November 1944: After a series of dangerous missions in the South of France, US Army Captain Billy Boyle is finally on leave, and is settling into a peaceful rest at the country estate of Sir Richard Seaton, the father of Billy’s British lover, Diana. Seaton Manor is a comfortable haven, and Billy is eager to spend a few precious days in Diana’s company pretending the war is far away.
