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.
