Death in Holy Orders on AllMovie

This mystery centers around an isolated British town in which a death at a theological college, previously ruled as accidental, is reopened for an extended investigation by Scotland Yard. Commander Dalgliesh, a former student at the college, conducts the necessary research at first simply as a matter of protocol, but he soon finds more mysterious and distressing revelations at every turn. Dalgliesh believes that the college and its visitors are in imminent danger, but by the time he is able to warn them, it may be too late.
