Wire in the Blood - Season 2: Episode 2

The remains of corpses are discovered whilst new foundations are being dug at the Norton Hotel, a building which stands on the site of an abbey, a fact which leads to a suspicion that these were religious killings. Then the hotel is burnt down and,as the first of a series of murders takes place, Carol asks for Tony's involvement. The strange thing is that these murders are identical to those committed some five hundred years earlier.
