April 1941. Romania. The Transylvanian Alps. The Dinu Pass.
To guard the northern approaches to an important strategic facility during Operation “Barbarossa,” a small detachment of German regular troops under the command of Captain Klaus Wormann was sent there. The detachment took up an ancient fortification structure that looked more like a medieval castle and served as an excellent observation post…
A grim castle greeted the newcomers with silence and struck their imagination with hundreds—thousands—of crosses covering its walls from the inside.
One soldier, driven by greed, tried to pry a cross loose from the wall and accidentally found a hidden passage…
And the horror began…
Something started killing German soldiers one by one every night…
Wormann requested reinforcements at headquarters, and an SS detachment under the command of Sturm-bannführer Erik Kempfer was sent to him.
But the arriving SS unit didn’t solve the problem; the murders continued…
Then Kempfer decided to take another route and began looking for someone who could tell him something about this castle…
And he manages to find the family of Theodor Kuzu, a professor at the University of Bucharest—but the trouble is that the professor and his daughter are Jews…
Meanwhile, a red-haired man is moving toward the castle, sensing that something terrible has awakened there, but he is still thousands of kilometers away…
Whether the Nazis can deal with the mysterious killer, whether the professor and his daughter will help them or not, whether the red-haired man will reach the castle and what role he will play in this story—you’ll find out by reading the book…
