Eschewing the series's usual modern-day setting, this stand-alone special moves the action to the more familiar Victorian London. Sherlock Holmes (Benedict Cumberbatch) and Dr. John Watson (Martin Freeman) must get to the bottom of a chilling mystery involving a seemingly ghostly killer in a wedding dress stalking the city streets in search of revenge. Amanda Abbington also stars. 86 min. Widescreen (Enhanced); Soundtrack: English Dolby Digital Surround; Subtitles: English (SDH); featurettes; interview; more.
