The Jackdaw Mysteries Series 3 Books Collection Set By S. W. Perry (The Angel's Mark, The Saracen's Mark, The Heretic's Mark)

The Angel's Mark

Heresy. Conspiracy. Murder...
London, 1590: Amidst a tumultuous backdrop of Spanish plotters, Catholic heretics and foreign wars, Queen Elizabeth I's control over her kingdom is wavering.
And a killer is at work, preying on the weak and destitute of London...
Idealistic physician Nicholas Shelby becomes determined to end these terrible murders. Joined in his investigations by Bianca, a beautiful but mysterious tavern keeper, the pair find themselves caught in the middle of a sinister plot.
With the killer still at large, Bianca finds herself in terrible danger. Nicholas's choice seems impossible - to save Bianca, or save himself...

The Saracen's Mark

England, 1593: Five years on from the Armada and Elizabeth's kingdom seems secure. But there is always a plot afoot...
Robert Cecil, the Queen's spymaster, needs Nicholas Shelby - reluctant spy and maverick physician - to embark on an undercover mission once again. One that he can't refuse, if he wants to keep Bianca Merton safe.

Crossing the seas to Marrakesh in search of a missing informer, Nicholas hunts the dingy back alleys and dazzling palaces for the truth. But his search reveals a deadly conspiracy, one far more difficult to survive than he'd ever imagined.
And back in London the plague has returned, ravaging the streets and threatening everything he holds most dear...

The Heretic's Mark

London, 1594. The Queen's physician has been executed for treason, and conspiracy theories flood the streets. When Nicholas Shelby, unorthodox physician and unwilling associate of spymaster Robert Cecil, is accused of being part of the plot, he and his new wife Bianca must flee for their lives.
With agents of the Crown on their tail, they make for Padua, following the ancient pilgrimage route, the Via Francigena. But the pursuing English aren't the only threat Nicholas and Bianca face. Hella, a strange and fervently religious young woman, has joined them on their journey.
When the trio finally reach relative safety, they become embroiled in a radical and dangerous scheme to shatter the old world's limits of knowledge. But Hella's dire predictions of an impending apocalypse, and the brutal murder of a friend of Bianca's force them to wonder: who is this troublingly pious woman? And what does she want?
