 The series, suggesting an expert blend of early Hammer Films and 1940s American film noir, interlinked the Doyle-Bell investigations with the published Doyle-Holmes mysteries to superb effect.Seen also during this period was his two-part "The Wyvern Mystery" (BBC, 2000), an adaptation of Sheridan Le Fanu's gothic horror-piece concerning, once again, women of the purest white, menacing men in dark old houses, and sudden appearances of 'mad women' from out of the shadows.While perhaps not the best of Le Fanu's work, its actual presentation seemed like a splendid small-screen tribute to the moody-gloomy Gainsborough melodramas of the 1940s.
