When the body of Pauline Brent is found hanging from a yew tree in a local graveyard, DS Wesley Peterson immediately suspects foul play. Meanwhile Wesley's archaeologist friend Neil Watson has excavated a corpse at his nearby dig, that of a young woman who—local legend has it—had been publicly hanged from the very same tree before being buried on unhallowed ground five centuries ago. Wesley is forced to consider the possibility that the killer knows the tree's dark history. Has Pauline also been executed rather than murdered? To catch a dangerous killer Wesley must discover as much as he can about the victim, but Pauline appears to have been a woman with few friends, no relatives, and a past she has carefully tried to hide.
