In 1679, Samuel Pepys is Secretary to the Admiralty, in charge of the navy, and at the right hand of King Charles. But also in 1679, England is awash with suspicion and fear. In this maelstrom of distrust, Pepys finds himself at the heart of a conspiracy, charged with treason and facing a crooked trial and potential execution. The only person who can save him is his brother, Balthazar, and Balthazar's twin children, Betty and Sam - precociously smart and deviously determined - and the three set off on a journey to prove Pepys' innocence. A clever and witty adventure which will make you think about Pepys in an entirely new light.
