young women are being kidnapped, then murdered. Harry Hunt, formerly of the Royal Society but now a rich gentleman, is falsely accused. To clear his name, he must rely on his abandoned scientific expertise and battle the full force of the British aristocracy.

1681. London cooks in summer heat. Bonfires are lit in protest against the King's brother, James, heir to the throne but openly Catholic. Rumours abound of a 'Black Box', said to conceal proof the King's illegitimate son is really the rightful heir.

When a wealthy merchant's daughter is kidnapped and murdered--even though a ransom was paid--the King orders Harry Hunt of the Royal Society to help investigate.

A second woman goes missing: Elizabeth Thynne, England's richest heiress. Her husband has a ransom letter from the same kidnappers.

Pressured by powerful men to find the killers and rescue Elizabeth, Harry uncovers a disturbing link to Bethlehem Hospital, better known as Bedlam.

But he is falsely accused of the crimes.

To prove his innocence, he must find the real culprits. Harry's search takes him from Rotherhithe to Whitehall Palace, and to the house of Sir Peter Lely, the famous portrait-painter, in Covent Garden.

And back to Bedlam.

He has the Monarchy's future in his hands.
