A professional, cinematic psychological thriller book cover. The scene features a dimly lit, high-end modern office hallway at night, with polished reflective floors. In the center, a silhouette of a man stands with his back turned, looking towards a flickering overhead light. A second figure, a woman, is partially visible in the reflection on the dark floor, looking terrified. The color palette is composed of deep midnight blues, cold greys, and a sharp, jarring splash of crimson red from a single glowing exit sign or a drop of spilled ink. The atmosphere is tense, claustrophobic, and suspenseful. High contrast, sharp details, photorealistic style, moody lighting, professional graphic design aesthetic, no text, no letters, no words, 1024x1024.
