04:47 a.m. Jeff opens his eyes. Sudden, complete, in a fraction of a second. Three decades in the military run deep within his nervous system. For a brief moment, he lies motionless in the armchair, staring into the darkness. As his eyes adjust to the low light, his mind is already running the old pattern. Once, this was the moment when the tactical situation would take shape: direction of threat, exits, cover, escape routes. Today, any threat is absent.

What remains is the armchair. The cold cup on the side table. The faint crackle of the dying fire. As Jeff closes his fingers into a fist, his body answers with the familiar ache in his joints. Arthrosis. His gaze shifts to the clock on the wall while outside, the forest remains black beneath the night.

At fifty-eight, he is used to getting by on a minimum of sleep, yet for the past seven months, he has spent every night here in this armchair. The bed in the next room has simply grown too large. His eyes settle on the bedroom door, but he remains seated. The left side of the mattress still carries the shape of her body. He yields the hollow to memory.

Two years ago, his wife died. Since then, his existence has narrowed to retirement, daily walks, and the same paths through the same woods. The days begin and end in a persistent emptiness. He lives in isolation in his house at the edge of the forest—the only place where the silence renders the loss bearable for a few hours.

He pulls himself up. The joints protest, first the knees, then the hips, then the hands, which claw around the armrests. Arthritis. A bitter weight lies in the word. It feels like a personal defeat, not like biological decay. For thirty-five years his legs carried him through mountains, deserts, jungles, and over concrete roofs. They always fulfilled what was demanded of them. At fifty-eight, his body takes its toll for those years. Pain is familiar. Pain is an old currency.

As he drags himself into the kitchen and puts water on to boil, a memory rises unbidden. A sober line from his personnel file cuts through the quiet: Team leader, unit KSK 7. Total time in service: 35 years, 4 months, 18 days.

Short and precise, exactly as he always preferred. But the weight of these lines does not appear in any file. He remembers how the Kommando Spezialkräfte—Germany’s elite Special Forces Command—recruited him at twenty, back then a bony mountain infantryman from the Allgäu who climbed faster than everyone else and did not stop when it hurt. Decades later, he operated as commander of a covert special unit whose name appears in no document and whose areas of operation appear on no map. He stays silent. Too many of the stories belong to people who are still alive, on both sides.

At some point his brain automates this analysis, like breathing happens on its own. He knows how to lead a small team through hostile territory, how to make decisions under time pressure when no decision tree helps anymore and only instinct remains. And how to live afterward with what he decided.

He knows the exact moment a life loses its way. At fifty-five, he walks away from the service—one year before Maria’s death. Back then, his body still carried him through every mission, but he reached the line that cannot be pushed. He could be the man who vanishes into the night, or the man who stands at home when it matters. For thirty-five years, he chose the first path. In the end, only a hollow loss remains—settling deep inside him, consuming every answer.

The kettle clicks. The sound snaps him back. He avoids looking at the frame on the wall; the sheer knowledge of it is enough to burn. A sudden tightness grips his chest—a heavy, familiar stirring from his days commanding the unit. He freezes, scanning the quiet room to pinpoint the threat. His eyes trace the familiar shadows and dusty contours of the furniture. Nothing. Every detail lingers in the usual stillness. With a brief shake of his head, he turns back to his coffee.

He drinks the coffee black and too hot, as always. The heat burns his tongue, but he accepts it like everything else that cannot be changed. Outside, the forest begins to lighten from black into a hazy gray. His property borders directly on the edge of the woods. One of the reasons he bought the house twenty years ago. Back then, when future plans were still something. Maria liked the garden. He liked the forest. Both have remained.

He gets dressed: hiking pants, fleece pullover, the old boots he should have thrown away long ago. Every hand movement goes slower than it should. The fingers do not respond immediately, the knees need a moment before they carry the full weight. He gives them a moment, thinking nothing of it. Thinking does not help with getting dressed. The way into the forest is his only ritual. Not out of enthusiasm. Not because nature heals or trees offer comfort or any of the things people say who only visit the forest on weekends. But because movement and the silence of the forest are the only state in which the brain stops playing the same loop. As long as the legs run, at least something runs.

He takes the known path that runs to the northeast. Red oaks, firs, between the trunks the low November twilight. The crowns hang heavy and soundless, the leaves on the ground are wet from the night, and his breath pulls small clouds into the cold. He knows every tree on this way. He could walk it blindfolded, and he has, once, as a test. An old reflex from a life he has left behind.

He is a hundred meters deep in the forest when his gaze locks onto the anomaly. Deep in the undergrowth, off the trail, a cold blue glow breaks through the dark. The light pulses with rigid, flawless constancy—swelling and fading. A blue point moves left to right, dies out, then starts over. Left to right. The precise, rhythmic sweep of a mechanism awaiting an impulse. His foot stops mid-stride. Three seconds, four. He watches. His mind—the rational side—registers the anomaly and finds no fit. He decides against investigating. Ninety-nine times out of a hundred, blue lights in the woods turn out to be something completely banal. He continues on his way, letting the glow disappear behind the bend.

It steps out of his field of vision, but his brain keeps working. In earlier times this part of his mind assigned guards and counted exits. Now it continues to process every change of light in the room.
