As Halloween approaches, we'll hear Sherlock Holmes and Dr. Watson face off against supernatural foes - or at least foes who appear to be supernatural. Werewolves, ghosts, vampires - none of them stand a chance against the world's greatest detective. We'll hear Tom Conway as Holmes and Nigel Bruce as Watson in "The Adventure of the Black Angus" (originally aired on ABC on October 19, 1946) and "The Adventure of the Carpathian Horror" (originally aired on ABC on April 14, 1947). Then, John Stanley and Alfred Shirley star in "The Case of the Sanguinary Spectre" (originally aired on Mutual on February 8, 1948) and "The Case of the Everblooming Roses" (originally aired on Mutual on May 16, 1948).
