Amidst the chaos of World War II…
In a land of brutality and bloodshed…
One death can still change everything.
 
In war-torn Yugoslavia, a beautiful young filmmaker and photographer—a veritable hero to her people—and a German officer have been brutally murdered.
 
Assigned to the case is military intelligence officer Captain Gregor Reinhardt. Already haunted by his wartime actions and the mistakes he’s made off the battlefield, he soon finds that his investigation may be more than just a murder—and that the late Yugoslavian heroine may have been much more brilliant—and treacherous—than anyone knew.
 
Maneuvering his way through a minefield of political, military, and personal agendas and vendettas, Reinhardt knows that someone is leaving a trail of dead bodies to cover their tracks. But those bloody tracks may lead Reinhardt to a secret hidden within the ranks of the powerful that they will do anything to keep.
 
And his search for the truth may kill him before he ever finds it.

The Pale House

by Luke McCallin

Published 1 July 2014
As the Nazi war machine is pushed back across Europe, defeat has become inevitable. But there are those who seek to continue the fight beyond the battlefield.

German intelligence officer Captain Gregor Reinhardt has just been reassigned to the Feldjaegerkorps—a new branch of the military police with far-reaching powers. His position separates him from the friends and allies he has made in the last two years, including a circle of fellow dissenting Germans who formed a rough resistance cell against the Nazis. And he needs them now more than ever.

While retreating through Yugoslavia with the rest of the army, Reinhardt witnesses a massacre of civilians by the dreaded Ustaše—only to discover there is more to the incident than anyone believes. When five mutilated bodies turn up, Reinhardt knows the stakes are growing more important—and more dangerous.

As his investigation begins to draw the attention of those in power, Reinhardt’s friends and associates are made to suffer. But as he desperately tries to uncover the truth, his own past with the Ustaše threatens his efforts. Because when it comes to death and betrayal, some people have long memories. And they remember Reinhardt all too well.

And now, Reinhardt will have to fight them once more.

The Divided City

by Luke McCallin

Published 6 December 2016
Luke McCallin, author of The Pale House and The Man from Berlin, delivers a dark, compelling thriller set in post-World War II Germany featuring ex-intelligence officer Captain Gregor Reinhardt.

A year after Germany’s defeat, Reinhardt has been hired back onto Berlin’s civilian police force. The city is divided among the victorious allied powers, but tensions are growing, and the police are riven by internal rivalries as factions within it jockey for power and influence with Berlin’s new masters.

When a man is found slain in a broken-down tenement, Reinhardt embarks on a gruesome investigation. It seems a serial killer is on the loose, and matters only escalate when it’s discovered that one of the victims was the brother of a Nazi scientist.

Reinhardt’s search for the truth takes him across the divided city and soon embroils him in a plot involving the Western Allies and the Soviets. And as he comes under the scrutiny of a group of Germans who want to continue the war—and faces an unwanted reminder from his own past—Reinhardt realizes that this investigation could cost him everything as he pursues a killer who believes that all wrongs must be avenged…

THE WESTERN FRONT, JULY 1918

Gregor Reinhardt is a young lieutenant in a stormtrooper battalion on the Western Front when one of his subordinates is accused of murdering a group of officers, and then subsequently trying to take his own life. Not wanting to believe his friend could have done what he is accused of, Reinhardt begins to investigate. He starts to uncover the outline of a conspiracy at the heart of the German army, a conspiracy aimed at ending the war on the terms of those who have a vested interest in a future for Germany that resembles her past. The investigation takes him from the devastated front lines of the war, to the rarefied heights of society in Berlin, and into the hospitals that treat those men who have been shattered by the stress and strain of the war. Along the way, Reinhardt comes to an awakening of the man he might be. A man freed of dogma, whose eyes have been painfully opened to the corruption and callousness all around him. A man to whom calls to duty, to devotion to the Fatherland and to the Kaiser, ring increasingly hollow...
