the ending and matching his facial features with those of the spectre. The film also makes use of visual and aural devices. For example, the appearance of the spectre is stressed by the vibrations of a bell in the signalbox and a recurring red motif connects the signalman's memories of a train crash with the danger light attended by a ghostly figure. Clark's final Ghost Story for Christmas, Stigma, was an original story by Clive Exton filmed around the stone circles at Avebury, Wiltshire. He had wanted to film James' "Count Magnus", the teleplay of which had been written by Basil Copper, but was unable to obtain the budget. Although he felt the substitute film was "effective", Clark had by this time left the BBC to go freelance, joining Yorkshire Television, where he and Exton made another James adaptation Casting the Runes in 1979. Locations The filming of the adaptations took place at a variety of locations. Clark notes that James gave him "a wonderful excuse to discover...places where you could best impart tension and atmosphere." East Anglia, where M. R. James set many of his stories, was the location for the two first films. The Stalls of Barchester was filmed at Norwich Cathedral and in the surrounding close. For A Warning to the Curious, "Seaburgh" (a disguised version of Aldeburgh, Suffolk) was filmed on the coast of North Norfolk at Waxham, Holkham Gap, Happisburgh, Wells-next-the-Sea and on the North Norfolk Railway. Clark recalls filming in North Norfolk in late February, with consistently fine cold weather "with a slight winter haze which gave exactly the right depth and sense of mystery to the limitless vistas of the shoreline there." Later locations include Ormsby Hall and the Pelham Mausoleum at Brocklesby, Lincolnshire for Lost Hearts, Wells Cathedral, the Orchardleigh Estate, Frome and its 13th century church for The Treasure of Abbot Thomas, Prideaux Place near Padstow for The Ash-Tree and the Severn Valley Railway near Kidderminster for The Signalman. For The Signalman, a replica Great Western Railway signal box was erected in the cutting on the Kidderminster side of Bewdley Tunnel, and Highley signal box was used for the interior shots. Music Adam Scovell, analysing the aural aesthetics of the BBC Ghost Stories, notes that although Clark talks about "stock music", the early adaptations make use of what were then new, avant-garde classical works found in the BBC's gramophone library at
