Suddenly while gardening

the long version

Detective Chief Superintendent Tom Pollard of New Scotland Yard visits a sleepy village in the English countryside for what he thinks will be a quiet holiday, but his plans are ruined when some hikers discover a very modern skeleton in an ancient Celtic gravesite. At first the local authorities think the skeleton is a gruesome practical joke, but when the evidence points to murder, they ask Pollard to take charge of the investigation - an investigation that is hindered by the aggressively uncooperative villagers, who lead him to believe that someone has something worse than a mere skeleton to hide.
