Jamaica. 1788. The next war has already begun.

When Captain William Rennie accepts a new commission aboard HMS Expedient, he expects little more than another thankless mission from the shadowy government agent Sir Robert Greer.

Instead, he sails into a deadly conspiracy.

French spies have infiltrated Britain's richest Caribbean colony. A government official is murdered. Secret intelligence disappears. And as fear spreads through the streets of Port Royal, Rennie and his First Lieutenant, James Hayter, discover an enemy plot that threatens the entire island.

With time running out, Expedient must hunt down the conspirators before their plans ignite a war that Britain is not yet ready to fight.

Packed with naval action, espionage, murder and authentic Age of Sail adventure, Port Royal is a thrilling HMS Expedient novel from Peter Smalley.
