Detective Superintendent Trewley and his female partner, Inspector Stone, investigate a suspicious gas leak that killed the brilliant but unpleasant scientist in charge of a top-secret project
Reread this week. A grumpy scientist is found dead in his home. Was it accident or murder? While he was certainly brilliant, he was hardly popular. Trewley and Stone of the CID can't find a single person who actually liked the man. And when they learn about his research, they find lots of motives to want him dead.
A good twist at the end makes up for some of the rather ordinary story and characterization.
