The doctors gave my three-year-old son just fourteen days to live, and I believed nothing could hurt me more than that

Inside the envelope was not a standard sheet of paper, but a series of three transparent sheets of film, each covered in tiny, intricate dots and lines, alongside a short, handwritten note on Sofia's personal stationery.

My beloved Luca,

If you are reading this, it means my time has run out, and our sweet boy is in mortal danger. I am so sorry I could not stay to fight beside you. I knew that if I confronted you directly, your rage would blind you to the subtlety of the threat. The person poisoning us does not want power; they want total destruction of the Moretti name.

The antidote to the digitalis refinement is not something you can buy at a hospital. It is a rare compound derived from the sap of the white lotus, processed with specific enzymes. I have hidden a six-month supply of the serum where we first realized we loved each other.

To find the name of the traitor, overlay these three transparent sheets over the map of Chicago hanging in your library. Align the three red dots with the locations of our three family safehouses. The intersecting lines will spell out the name.

Save our boy, Luca. And forgive me for keeping secrets.

Forever yours, Sofia.

Tears, hot and unbidden, burned my eyes. I carefully tucked the transparent films into my inner pocket, my mind racing. Where we first realized we loved each other. It wasn't the cathedral where we were married, nor was it the grand estate in Lake Forest. It was a tiny, overgrown conservatory behind an abandoned villa in Evanston, a place where we had sought shelter during a blizzard years ago.

I turned to look at Matteo. His breathing was shallow again. The momentary energy from the cake was wearing off, and the shadow of death was creeping back over his small face. Fourteen days? No. Looking at his pale skin, I knew we didn't even have that long.

Elena slipped into the room like a ghost, closing the door quietly behind her. "You have the location of the antidote?"

"I know where the medicine is," I whispered, setting the note down. "But I need to get to Evanston without drawing attention. If the traitor realizes I know about the poison, they will strike before I can get the serum into Matteo's system."

"Then you go alone, through the old utility tunnels beneath the wine cellar," Elena suggested, her dark eyes flashing with sharp intelligence. "I will stay here with Matteo. I brought a mild neutralizing agent concealed in the lining of my bag—it won't cure him, but it will slow down the absorption of the toxin for forty-eight hours."

I stared at her, assessing this woman who looked so much like my lost wife, yet carried a fierce, hardened edges that Sofia had always managed to conceal. "Why are you risking your life for us, Elena? You didn't know Matteo."

"He has Sofia's blood," she said simply. "And yours. That makes him family. In my world, family is the only thing worth dying for."

I nodded once, a silent vow passing between us. "If anyone tries to force their way into this room while I am gone, use the weapon under the second drawer of the nightstand."

"I brought my own," she replied coldly, reaching into her dress and revealing a sleek, silenced 9mm tucked beneath her apron strap.

A small smile touched my lips despite the darkness surrounding us. She truly was Sofia's sister.

Ten minutes later, dressed in black tactical gear and leaving my phone behind to avoid being tracked, I slipped down into the damp, stone-lined basement of the estate. The wine cellar was cold, smelled of oak and old earth, and contained a hidden iron grate that led out into the municipal drainage network.

I popped the latch, squeezed through the dark tunnel, and emerged three blocks away in an abandoned alley where an unregistered vehicle was waiting. I started the engine and tore through the rain-slicked streets toward Evanston.

The city was a blur of neon lights reflecting on wet asphalt. Every traffic light felt like an eternity; every second spent was a second stolen from Matteo's fragile life. My hands gripped the steering wheel so hard my knuckles turned white.

When I reached the abandoned villa in Evanston, the iron gates were rusting, swinging in the night wind with a eerie creak. I parked down the street, drew my silenced pistol, and crept through the untamed overgrown grounds toward the glass conservatory at the rear.

The structure was mostly intact, though several glass panels had shattered, allowing rain and ivy to invade the interior. In the center stood a marble fountain, long dry, surrounded by dying vegetation.

I approached the fountain, remembering that night five years ago when Sofia and I had huddled near a makeshift fire, wrapped in a single wool blanket, making promises we thought eternity couldn't break.

I knelt by the base of the fountain, searching for the hidden panel Sofia had mentioned in her private letters. Beneath a thick layer of moss, my fingers felt a loose piece of granite. I pried it free, revealing a small, waterproof steel box tucked deep into the foundation.

My heart slammed against my chest. I reached in and pulled the box out.

Just as my fingers wrapped around the handle, I heard the distinct click of a gun hammer being cocked directly behind my head.

"I always knew you were a sentimental fool, Luca," a voice rasped through the dark.

I froze. The voice belonged to someone I had known for fifteen years. Someone who sat at my dinner table, who commanded my guards, and who had helped carry my wife’s coffin to her grave.
