Hailed as the most faithfully filmed adaptation of Sir Arthur Conan Doyle's legendary characters. This acclaimed series stars Ronald Howard as the world-famous sleuth and H. Marion Crawford in a different portrayal of Dr. Watson than usual. THE CASE OF THE PENNSYLVANIA GUN: Holmes and Watson travel to the Sussex countryside to fish - literally - for clues in a shotgun murder of John Douglas, what Holmes calls The Case of the Other Dumbbell. Holmes slides down a bannister in the course of his investigation. He not only deduces who the murderer is, but also who the victim is.
