On the evening of 17 October 1678 the body of Sir Edmund Berry Godfrey, a Westminster Justice of the Peace, was discovered in a ditch near Primrose Hill. He had been pierced with his own sword and apparently strangled. His death lead to a widespread popular hysteria about a "Popish Plot". Although a magistrate famous for his fierce rectitude, Godfrey was closely involved with the alternative healer and "stroker", Valentine Greatrakes and also played a part in many plots and and intrigues centred on the uninhibited court of Charles II and Restoration London. His death brought to a head a series of rumours about Catholic plots to kill Charles II and install his brother, James, Duke of York, on the throne. Identified as the victim of a Jesuit hit-man, Godfrey became overnight a Protestant martyr and cult figure.

On a cold October afternoon in 1678, the Westminster justice of the peace Sir Edmund Berry Godfrey left his home in Charing Cross and never returned. Within hours of his disappearance, London was abuzz with rumours that the magistrate had been murdered by Catholics in retaliation for his investigation into a supposed 'Popish Plot' against the government. Five days later, speculation morphed into a moral panic after Godfrey's body was discovered in a ditch, impaled on his own sword in an apparent clumsily staged suicide. This book presents an anatomy of a conspiratorial crisis that shook the foundations of late Stuart England, eroding public faith in authority and official sources of information. Speculation about Godfrey's death dovetailed with suspicions about secret diplomacy at the court of Charles II, contributing to the emergence of a partisan press and an oppositional political culture in which the most fantastical claims were not only believable but plausible. Ultimately, conspiracy theories implicating the king's principal minister, his queen and his brother in Godfrey's murder stoked the passions and divisions that would culminate in the Exclusion Crisis, the most serious challenge to the British monarchy since the Civil War.ng the king's principal minister, his queen and his brother in Godfrey's murder stoked the passions and divisions that would culminate in the Exclusion Crisis, the most serious challenge to the British monarchy since the Civil War.ng the king's principal minister, his queen and his brother in Godfrey's murder stoked the passions and divisions that would culminate in the Exclusion Crisis, the most serious challenge to the British monarchy since the Civil War.ng the king's principal minister, his queen and his brother in Godfrey's murder stoked the passions and divisions that would culminate in the Exclusion Crisis, the most serious challenge to the British monarchy since the Civil War.
