The Inspector has received a telephone call requesting his attendance at the local university, for an audience with one of the top professors in the world. Professor Richards is regarded as one of the greatest brain specialists alive. On arriving at the university, the Inspector learns that another of the university's professors has recently passed away from heart disease. But, before he died, he requested that his brain be donated to medical science, which is no surprise. What is a shock, is that the professor's body has been stolen and is being held for ransom!
