Doctor Who and Mary Shelley - a match made in heaven? One might think so given the amount of times the two have crossed paths, with the 19th century writer having previously crossed paths with the Tenth Doctor in the Battles in Time comic strip and been a fully-fledged companion to the Eighth Doctor in a series of Big Finish audio adventures. But without arguing just which of these are considered canon, it’s time for a new first encounter with Doctor 13 in The Haunting of Villa Diodati. Edging one step closer to the two-part series finale, this episode from writer Maxine Alderton and director Emma Sullivan promises to be the injection of gothic horror series 12 has lacked thus far.
