When Dr Nathan Frost, a lecturer in German literature at Oxford University, is invited to a lavish party at the country house of a wealthy businessman, he knows there'll be a price to pay. After all, as an expert on the legend of Faust and Mephistopheles, he can recognise a deal with the devil easily enough. But even he's not expecting such a sinister end to the evening.

Called to investigate a suspicious death at a country house, Detective Inspector Bridget Hart is surprised to find a government minister among the party guests. Her team must navigate powerful interests to find the truth. But in a world of favours, backhanders and corruption, nothing is as it seems and nobody can be trusted.

Set amongst the dreaming spires of Oxford University, the Bridget Hart series is perfect for fans of Elly Griffiths, JR Ellis, Faith Martin and classic British murder mysteries.
