"Nott will get the boy over my dead body," Lucius said. "First of all there is no inheritance unless I'm dead and I'm not planning on dying any time soon. Two, I'll just have to change my will. I can see why he waited to tell me. If I didn't know and died, then he could claim something, but if I know and don't include him, then he or Nott can't claim a knut." He just had to stay alive, which might be the way to present it to Cissa. If he died without a new will, Draco might not have everything. There, that should do the trick for now.
He kept thinking about how to survive when the boy arrived and just like that he had no doubt who this child was. He looked like a Malfoy, the blond hair, the grey eyes, the chin. It would only be a matter of time before people connected the dots. "Leonardo, I'm told," Lucius said. "I'm-" Your father? A dead man walking? "Lucius Malfoy," he said, extending a hand. "It's a pleasure to meet you."
