Not quite reaching the standards of its predecessor Thus Spake Bellavista, this turn at the fount of Prof. Bellavista's wisdom has him and his variously inept followers trying to track down a murderer. While using the Prof's telescope to watch Halley's comet, the Bellavista coterie focuses on what appears to be a murder in a nearby apartment. Though Sherlock Holmes would shudder at their investigative techniques, at least the city of Naples is shown to good advantage.
