Watson is back to tell us about the great sleuth Sherlock Holmes and the locked-room mystery of "The Adventure of the Speckled Band." Years after a young woman dies with no sign of foul play in a room that appears completely locked, her worried twin sister sics Holmes on the complex case. David Timson embodies Watson's intellectual British lilt. With whispered galloping pacing, Timson builds suspense. In contrast, he shapes characters and the details of the case with careful, deliberate enunciation and clarity of voice.
