A well told ghost story. It has a flashback in a flashback structure that works well and has a fine creepy atmosphere which leaves some things to the imagination adeptly. The performances are not showy which adds to the subdued tension. I did particularly like Colin Gordon as the scientific ghost hunter Burdon and Jane Hylton as the story teller with a secret. Stanley Black provides a suitable music score. It shows what can be done with a small budget and careful creativity. Vernon Sewell the director is an under rated film maker.
