Dance of Death [EPUB ebook] 

Newly returned from an eventful mission to Scotland – and eager to be reunited with his family – Roger the Chapman is far from pleased when Timothy Plummer, Spymaster General to the King, commands him to undertake another mission. He is to accompany the beautiful but manipulative Eloise Gray on a special journey to Paris, pretending to be her husband.
Though Plummer is reluctant to reveal the motive behind this appointment, Roger understands that the French king is making overtures to the Duke of Burgundy on behalf of the Dauphin – a move which could wreck the relationship with England’s staunch ally and most important customer for her wool exports.
