Twelfth-century anatomist, Adelia Aguilar must once again examine the dead as gruesome events are beginning to unfold...

Henry II's favourite mistress, Rosamund Clifford, has been poisoned - and, rumour says, by his jealous wife, Eleanor of Aquitaine. If Henry believes the stories, England will be torn apart as King battles Queen.

In a race against time to prove Eleanor's innocence, and with a dangerous assassin on the loose, Adelia has never faced greater danger. The armies that might cause civil war lie behind her. The icy winds of a dreadful winter blow around her. And ahead she must brave the thorns of the impenetrable labyrinth that surrounds Fair Rosamund's tower, and decipher the mystery of the dead woman who lies frozen within.
