Young Gyorgy Hevesy arrives in England to research radioactivity, specifically Radium-D, which later turns out to be radioactive lead. He contemplates injecting it into living beings to track their metabolism. One day, to prove to the cook that the meatballs were leftover meat from days before, he sprinkles it on the meat, and the next day he arrives with an instrument newly invented by his colleague Hans Geiger. And, as she had suspected, he hears a concert of clicks. The woman, rather than being offended, is flattered to have been involved in such a sophisticated and cutting-edge experiment.
