Locked doors had never been a problem for Dan O'Leary alias Ian Kerry. The door to his son's apartment gave in after less than thirty seconds. O'Leary was worried. He had spent six months in hiding. After that bloody traitor had given Scotland Yard the proof that he had built the bomb that took out Mountbatten he had decided to slope off for a while. He hadn't told Edward – the bomb expert knew from experience that the best protection for his near and dear ones was lack of knowledge. Ed already knew way too much. The old man hadn't been able to resist the urge to pass on his legacy: A unique style of brilliant bomb building. The boy had been an outstanding apprentice. Unfortunately he wasn't well – that was why O'Leary had finally decided to come back.
A look into the bedroom confirmed his gravest concerns. Edward, a mere shadow of himself, was lying in bed. His breath was so shallow, the sheet hardly moved. Quietly, the father sat down on the bed frame. His son's eyes fluttered open as he felt the presence of the other man. "Dad", he whispered. "You're back."
"Don't speak", O'Leary whispered, caressing his boy's sweaty forehead. If he had known how sick his child was, he would have never gone away. But Ed had hidden his true state of health very well from him.
"I was so worried", Edward whispered. "You just vanished… I thought something had happened to you. After three days I reported you missing, but the police didn't lift a finger. I'm so glad it worked…"
This last sentence confused the old man. "What worked, Edward?", he asked. For the first time, he consciously took in his environment. He had concentrated so hard on his only son, he had simply overlooked all the way too familiar utensils, wires and circuit boards lying scattered on a big table by the window. "Oh my god, Edward, what did you do?", he gasped. His son squeezed his hand. A single tear ran down his cheek.
