A professor has conducted extensive research into a lost civilization on the Iran/Afghanistan border and after years of obscurity is possibly a candidate for the Nobel Prize as a result of his findings.

One day the professor is visited at his home by a young researcher who has evidence that contradicts some of his findings - something that could eliminate his chance for the prize and further recognition.

Soon, there will be a murder investigation.

For a while, I thought I was listening to a radio version of "Columbo."
