The year after defeating the Spanish Armada, England retaliates. The expedition to Portugal sets out to destroy what remains of Spain's Atlantic fleet, drive the Spanish out of Portugal, put the claimant Dom Antonio of Aviz on the throne, and seize the Azores.

When the violent arrest of an innocent apprentice sparks a riot in Southwark during the summer of 1592, more lies behind it than a simple grievance. Increasing poverty, vagrancy, and crime in a restless London compel a nervous Privy Council to close the playhouses, forcing Lord Strange's Men to go on tour, while hostility to foreign refugees, aggravated by Marlowe's play, The Jew of Malta, adds to the danger on the streets for Strangers like Kit Alvarez. Other dangers are more subtle. The ensnaring of young men by illegal loan sharks and the circulation of damning accusations, both public and...
