Narrator: Camel, America's first choice among cigarettes presents Topper starring as Marianne Kerby, the liveliest ghost in town, Anne Jeffreys; as George Kerby, the liveliest ghost in town, Robert Sterling; and Leo G. Carroll as Topper. Oh yes, and the deadliest ghost, Neil. And there are only three people in the world who can see them. You and I and Cosmo Topper.
