The Tudor secret : [the Elizabeth I spymaster chronicles
Brendan Prescott was brought to court to serve in the household of the powerful Dudley family. He becomes ensnared in court politics and recruited as double agent to spy for Elizabeth I and her protector William Cecil. Who do you trust when everyone seems like the enemy? Half truths, lies and murder confront Prescott as he discovers pieces of his mysterious past. This is the first book in the Elizabeth I spymaster chronicles and Brendan’s unknown background is the compelling mystery that hooked this reader.
