One elderly victim. Two weapons. But only one person in custody.

When Margaret Thompson was killed, it felt like an open and shut case. But new evidence suggests the key suspect didn’t do it alone.

A killer could still be out there.

So why’s Professor Ruth Morgan taking a casual walk in the park?

This episode includes references to death, violence and dissection, which some listeners may find distressing. Our victim is fictional, but the science and the scientists are very real.
