The third in this exciting spy series set in Tudor England, amid the intrigue and danger of Henry VIII's royal court, from the authors of books in the bestselling Beast Quest series.
It's 1532 and the royal court of King Henry VIII is on the move - and in danger!
A terrible storm forces the court to shelter in a nearby castle. The King is in disguise, and he's not the only person with a secret. Death stalks the castle - but is it the dreaded plague or something even more sinister? When a servant is found dead, it's clear that something terrible is going on.
Can young spy, Jack Briars, and his friend, Cat Thimblebee, solve the mystery before the King himself becomes a target?
