The Queen’s spymaster, Francis Walsingham, turns to Senior Constable, Thomas Lincraft, to uncover the plot and identify the conspirators.
Summoned to the capital, Lincraft revisits the streets of London, and ventures into its criminal underworld, ably assisted by his friend and fellow Constable - Giles Bradbury.
Assuming various false identities, and narrowly escaping the enemy’s clutches, the Queen’s Constables pick up the trail of the smugglers.
For Lincraft, his duties open old wounds as he finds himself reacquainted with a figure from his past, and confronting harrowing memories from his youth. It is finally a chance to settle an old score and see justice served.
The smuggled priests are pursued to their ultimate destination but will it be the constables, rather than their quarry, who must face the executioner's noose?
