A 2016 World Book Night selection.
The fourth in the series featuring Giordano Bruno, mathematician, philosopher, heretic and spy, and solver of murders in Elizabethan England. In previous novels Bruno encountered John Dee, Nostradamus and Walsingham. He’s good friends with Philip Sidney (historically rumoured to be the Queen’s lover) and in this episode he is under the feet of Sir Francis Drake.
Bruno’s deep and wonderful mind make these books more meaty than an historical romp and more vividly complex than the run of cosy crime. A spirit of adventure and true love of the period infuses the prose. Reading this alone won’t spoil your enjoyment of the mystery but to get the full flavour I recommend starting with Heresy the first in the series.

August, 1583. Giordano Bruno, a heretic fleeing the Inquisition, finds a new life working as a spy for Sir Francis Walsingham. Along with his friend, Sir Philip Sidney, Bruno travels to Plymouth on the Queen's behalf.
