"He wrote of the plans he was making to "ensure the dispatch of the usurping competitor" I asked Joseph who Babington meant by "competitor". It is Queen Elizabeth, and by "dispatch", he means murder. Babington and his friends intend to kill the Queen."
The Queen's Spies: The Diary of Kitty Lumsden is a fictional diary in the My Story series. It was written by Valerie Wilding and first published in December 2005. The book was republished in May 2008 as To Kill a Queen. It was last My Story book, until the series was relaunched with Princess of Egypt in 2008.
"It's the 1580s. Queen Elizabeth's enemies plot to kill her and place Mary Queen of Scots on the throne. While Kitty's father works on secret projects for Elizabeth, her brother's mixing with suspicious characters. As Mary's supporters edge closer by the minute, Kitty fears the worst... that they'll all be thrown into the Tower."
One day, Kitty's favorite brother, Joseph brings home a friend, Anthony Babington. On one of his visits, Babington talks with the Lumsdens' about Mary Stuart, "so much so that I began to wonder if he was not half in love with her." After learning by chance that he is Catholic, Kitty becomes suspicious of Babington. The Catholics of England wish to depose the Protestant Elizabeth and crown Mary Stuart, a Catholic.
The Lumsdens' are often visited by the Queen's secretary of state, Francis Walsingham, whom Kitty also suspects of being Elizabeth's spy. Francis brings one of his associates, Thomas Phelippes, an expert at deciphering codes. Kitty gets the idea to write messages in code to Edmund in order to avoid his nosy sister, Kathryn. Meanwhile, Babington goes abroad with his friends, returning several months later.
Kitty overhears her father and brother, Richard speaking about Francis's plan to intercept Mary's letters. Later, she learns about a priest named Ballard, who is plotting with the Spanish. Eventually, Ballard and Babington are arrested and found guilty. However, thanks to Francis's careful planning, Mary Stuart is also accused to being involved with the plot. A month after Babington's execution, Kitty and her family go to Greenwich Palace, where they meet the Queen.
