Pagan revelry and morris dancing in the middle of a very cold winter set the scene for one of Ngaio Marsh’s most fascinating murder mysteries.

When the pesky Anna Bünz arrives at Mardian to investigate the rare survival of folk-dancing still practised there, she quickly antagonizes the villagers. But Mrs Bünz is not the only source of friction – two of the other enthusiasts are also spoiling for a fight.

When the sword dancers’ traditional mock beheading of the Winter Solstice becomes horribly real, Superintendent Roderick Alleyn finds himself faced with a case of great complexity and of gruesome proportions…
