In a world where no one can be trusted and secrets are currency, one woman stands without fear.
Mallory Bright is the only daughter of London’s master locksmith. For her there is no lock too elaborate, no secret too well kept. Sir Francis Walsingham, spymaster and protector of Queen Elizabeth – the last of the Tudor monarchs – and her realm, is quick to realise Mallory’s talent and draws her into his world of intrigue, danger and deception. With her by his side, no scheme in England or abroad is safe from discovery; no plot secure.
But Mallory’s loyalty wavers when she witnesses the execution of three Jesuit priests, a punishment that doesn’t fit their crime. When Mallory discovers the identity of a Catholic spy and a conspiracy that threatens the kingdom, she has to make a choice – between her country and her heart.
Mallory, however, carries her own dark secrets and is about to learn those being kept from her – secrets that could destroy those she loves.
Once Sir Francis’s greatest asset, Mallory is fast becoming his worst threat … and everyone knows there’s only one way Sir Francis deals with those.
