Sherlock Holmes in the 22nd Century

S01E07 The Adventure of the Sussex Vampire Lot

In New London, a flamboyant vampire is wreaking havoc by disrupting computer systems, manipulating codes, and breaching secure vaults, leaving chaos in his wake. The only lead comes from unsettling footage of the vampire smirking at the camera while crushing a computer disk. Lestrade, with her characteristic flair for destruction, goes after the Sussex vampire, which amuses the detective. Diedre offers a fresh perspective, noticing a peculiar detail about their adversary while analyzing old horror films and clips of the disk-crushing incident. Holmes, Watson, and the Baker Street Irregulars track the data-devouring villain to his sewer hideout, where they encounter an old acquaintance of Holmes who is also investigating the vampire.
