From the No.1 Sunday Times bestselling author of The Ashes of London comes the next book in the phenomenally successful series following James Marwood and Cat Lovett.

A dangerous secret lies beneath Whitehall Palace…

Brother against brother. Father against son. Friends turned into enemies. No one in England wants a return to the bloody days of the Civil War. But Oliver Cromwell’s son, Richard, has abandoned his exile and slipped back into England. The consequences could be catastrophic.

James Marwood, a traitor’s son turned government agent, is tasked with uncovering Cromwell’s motives. But his assignment is complicated by his friend – the regicide’s daughter, Cat Lovett – who knew the Cromwells as a child, and who now seems to be hiding a secret of her own about the family.

Both Marwood and Cat know they are putting themselves in great danger. And when they find themselves on a top secret mission in the Palace of Whitehall, they realize they are risking their lives…and could even be sent to the block for treason.
