Keeping a secret from the Greek Tycoon

"Hello..." There was genuine sadness in her voice, but I could not be too sure. I reclined in the chair, feet propped up, glaring at my P.A. I did not understand why she thought I should be the one to handle it. What exactly had the woman said? Static on the line interrupted my train of thought, and I remembered I was on a call. "Sorry... who is this?" "It doesn't matter. Just come. He needs you." Her incoherent sentences annoyed me, but I probed further since I hadn't the slightest idea what she meant. "I'm sorry, who needs me?" "Adonis. Your son." The female voice retorted. Her answer amused me. This wasn't the first time I'd gotten calls like this, but it had to be the most absurd. I'd gotten "I'm carrying your baby" and "I have our tape," but this? Comedy gold. Combing my fingers through my hair, I told her point-blank. "Sorry, miss. You've got the wrong person. I use condoms, and there is no way I'd have a son I didn't know existed." I brought the phone down, about to hit the red button, when her pleading voice stopped me. "I beg you, Gregor Vallis. Adonis needs a blood donor and needs one now. He might die soon, and I know you don't believe anything I'm saying, but you have to. Gregor, you have a son dying right now at Petrina Memorial, and right now, you're his best shot at a match in time. Don't let him die..." There was something in her voice. The desperation… The honesty... She could not be lying, or maybe I was the one being crazy here. But how could I have a son?
