A vivid and gripping historical thriller set in Elizabethan England introducing Giordano Bruno, philosopher, scientist and spy for all fans of C.J.Sansom and The Name of the Rose.

In Elizabeth's England, true faith can mean bloody murder...

Oxford, 1583. A place of learning. And murderous schemes.

The country is rife with plots to assassinate Queen Elizabeth and return the realm to the Catholic faith. Giordano Bruno is recruited by the queen's spymaster and sent undercover to expose a treacherous conspiracy in Oxford - but his own secret mission must remain hidden at all costs.

A spy under orders. A coveted throne under threat.

When a series of hideous murders ruptures close-knit college life, Bruno is compelled to investigate. And what he finds makes it brutally clear that the Tudor throne itself is at stake...

Heretic, maverick, charmer: Giordano Bruno is always on his guard. Never more so than when working for Queen Elizabeth and her spymaster - for this man of letters is now an agent of intrigue and danger.
