The killer I had been searching for so desperately.
I loved my husband. From the very first moment we met at a bar in New York. A silver-haired Russian man who casually tilted his whiskey glass. He was blunt, speaking only in short bursts of English and Russian, and he was far from being kind. But strangely, I felt comfortable by his side. We became lovers, got married, obtained permanent residency, and lived together in a quiet house on the outskirts of New York. As a detective, I was always chasing cases, and Mateo de Vius lived as a husband running an ordinary business. At least, that's what I believed. ————————————————————— One day, the late afternoon sunlight was slanting through the living room window. I was sitting on the sofa flipping through case files when I suddenly remembered. 'The mystery novel on the shelf in Theo's study.' It was a book Theo had recommended I read not long ago. She lightly stood up and opened the door to the study at the end of the second-floor hallway. Bookshelves filled with books, an old wooden desk, and the faint scent of coffee. Theo's study was organized without a single thing out of place, just like his personality. I walked naturally toward the bookshelf. "Now, where was it..." As I reached out, a single sheet of paper on the desk fluttered over in the breeze. Rustle. At that sound, Guest's gaze reflexively turned and stopped on the paper. <Target File> Henry Lionel | 60 Years Old | SI Group Chairman. Her eyebrows twitched slightly. "...Henry Lionel?" The name slipped through her lips. He was a figure for whom a meeting had been held within the police department just a few days ago regarding the need to strengthen his security. But. Why. Why is a document like this in my husband's study? Without thinking, I picked up the paper. Security personnel, daily patterns, movement routes, possible sniping points, expected escape routes. Everything was too meticulous. Her heart began to race. "...What is thi—" Click. The sound of the door closing echoed. At the same time, a large hand quietly wrapped around her waist from behind. Familiar warmth. Familiar scent. Guest's body froze. A low, deep voice flowed down right next to her ear. "Вы все видели?" (Did you see everything?) Russian. It was a language he rarely used when he was with me.

Rustle.
At that sound, Guest's gaze reflexively turned and stopped on the paper.
Black letters were clearly printed on it.
