The Reluctant Assassin by Fiona Buckley
When Ursula's young son is kidnapped, she is lured into an impossible dilemma.
March, 1581. Queen Elizabeth is once again being urged to consider marriage to the Duke of Alencon, a French Catholic twenty years her junior. The prospect of the match is causing unrest throughout the kingdom.
Ursula Blanchard, however, has more immediate matters to worry about when her nine-year-old son is snatched away while out riding. If she is ever to see him again, Ursula must undertake an impossibly difficult and dangerous mission - and commit an act of high treason. Can she rely on her half-sister, Queen Elizabeth, for help?
