Tom Conway's best effort

We have enjoyed Tom Conway as The Falcon in the series of movies. Considering that he had to step in and replace his brother, George Sanders, who was an outstanding actor, that was a tough task. However, I don't know but what Conway's best effort was in replacing Basil Rathbone as the radio Sherlock Holmes. Rathbone, of course, WAS Holmes, and following up a legend is always difficult. However, Conway did a creditable job, imitating Rathbone's voice style approximately, if not exactly.
