In the 60's he actually had a story planned about an experimental atomic pill which is invented to help people survive a nuclear war. Tintin is in a minor car accident and the only injured person slips something in his pocket. A few days later everyone involved in the accident has had their homes robbed by mysterious figures. It turns out the man gave Tintin the formula to the atomic pills and now various foreign agents are after him.
