**Should Read as 4.5 Stars!**
Read this book in 2011, and its the 1st volume of the "Thomas Chaloner" series, from the author, Susanna Gregory.
The book is set in AD 1662, following the death and downfall of the Protector, Oliver Cromwell, and after the Restoration of King Charles II.
Our main protagonist is, Thomas Chaloner, spy of his former powerful boss, John Thurloe, and after coming home from Holland he's looking for employment.
Although his erstwhile boss, John Thurloe, has many enemies at court, he recommends to Thomas Chaloner a certain Lord Clarendon, in return that Thomas keeps him informed of any plots against him.
After been accepted by Lord Clarendon, Thomas discovers that another ex-employee has been sent to White Hall by Thurloe, only that man is now dead, actually murdered near the Thames.
When Thomas starts to investigate this murder, he's also being sent to the Tower by Lord Clarendon to discover the gold that's buried there by the last Governor, as the rumours suggest, but will find nothing instead.
But what he will discover uppermost is that people in power are ruled by greed and self-interest and that they have no compassion about others, and so Thomas has to fend for himself if he wants to survive this mission of conspiracy and death.
All in all a very interesting begin of this series with Thomas Chaloner and John Thurloe as the two most important protagonists at the moment, and its a mystery with quite some twists and turns, before a superbly executed plot will reveal the culprit(s) behind this conspiracy.
Highly recommended, for this is a gripping start of this exciting series, and that's why I like to call this first episode: "A Very Thrilling Conspiracy!"
