From the CWA Historical Dagger Award-nominated author of The Angel's Mark in 2019 and The Serpent's Mark in 2020 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... ________________________ Praise for The Jackdaw Mysteries, a CWA Dagger finalist series 'S.
