In the spring of 1802 Richard Bolitho is summoned to the Admiralty in London and given his orders for a difficult and, to him, distasteful task. Even an advanced promotion to vice-admiral to make him one of the youngest ever appointed does not compensate for his sudden and thankless mission. Bolitho and his wife are expecting their first child, and for once he is loath to quit the land for the demands of duty. The Peace of Amiens, signed a few weeks earlier, is already showing signs of strain as the old enemies wrangle over the return of colonial possessions won and lost during the war. In the little sixty-four-gun Achates Bolitho sails West for Boston, and thence to the Caribbean where he must hand over the island of San Felipe to the French. Bolitho discovers that to be a man of diplomacy is not enough, and as threat and counter-threat weave a web of intrigue around his lonely command he balances success against the danger to the men who must follow him even to the cannon's mouth.

In March of 1814, Admiral Sir Richard Bolitho returns to England from several months' rigorous patrolling off the North American coast. The bitter and inconclusive war with the United States has not yet ended, but news of Napoleon's defeat and abdication has stunned a navy and a nation bled by years of European conflict. Victory has been the impossible dream and now, for Bolitho, a vision of the future and a personal peace seems attainable. He remains, however, an admiral of England, and an unsympathetic Admiralty dispatches him to Malta. Perhaps this appointment is a compliment, perhaps a malicious ploy to keep him from the woman he loves and the freedom for which he craves? He cannot know, but the voice of duty speaks more insistently even than the voice of the heart, and in this familiar sea where both glory and tragedy have touched his life, Bolitho must confront the future, the renaissance of a hated tyrant, and the fulfilment of destiny.

Vice-Admiral Sir Richard Bolitho returns to England after the capture of Martinique, and finds a brief respite from war and politics in the arms of his mistress, Lady Catherine Somervell. But the affairs of nations allow little time for personal happiness, and to his surprise and dismay Bolitho is ordered almost immediately to the Indian Ocean, where the shadow of a new conflict already darkens the horizon as the old enemy, France, forges an uneasy alliance with America and threatens British trade routes. Haunted by the deaths in their country's service of Nelson and Collingwood, and by his own vivid memories of shipwreck and tragedy, Bolitho is well aware of the price of admiralty, and for the first time considers the possibility of life not only beyond the reef but beyond the sea itself.

In the spring of 1797 Richard Bolitho brings the 100-gun Euryalus home to Falmouth to be flagship of the hastily formed squadron which has been chosen to make the first British re-entry to the Mediterranean for nearly a year. As flag captain, Bolitho is made to contend with the unyielding attitudes of his new admiral, as well as the devious requirements of the squadron's civilian advisor. England is still stunned by the naval mutiny at Spithead, in which Bolitho's admiral was personally involved, and as the squadron sets sail the air is already alive with rumour of an even greater uprising in the ships at the Nore. Only when the squadron is drawn to a bloody embrace with the enemy does the admiral see the strength in Bolitho's trust and care for his men – but by then it is almost too late for any of them.

In September 1800 Richard Bolitho, a freshly appointed rear-admiral, assumes command of his own squadron – but, as the cruel demands of war spread from Europe to the Baltic, he soon realizes that his experience, gained in the line of battle, has ill-prepared him for the intricate manoeuvring of power politics. Under his flag the Inshore Squadron has to ride out the bitter hardship of blockade duty and the swift, deadly encounters with the enemy. An old hatred steps from the past to pose a personal threat to him, but at the gates of Copenhagen, where his flag flies admidst the fury of battle, Bolitho must put all private hopes and fears behind him.

February 1806 … The frigate carrying Vice-Admiral Sir Richard Bolitho drops anchor off the shores of southern Africa. It is only four months since the resounding victory over the combined Franco-Spanish fleet at Trafalgar, and the death of England's greatest naval hero. Bolitho's instructions are to assist in hastening the campaign in Africa, where an expeditionary force is attempting to recapture Cape Town from the Dutch. Outside Europe few have yet heard of the battle of Trafalgar, and Bolitho's news is met with both optimism and disappointment as he reminds the senior officers that, despite the victory, Napoleon's defeat is by no means assured. The men who follow Bolitho's flag into battle are to discover, not for the first time, that death is the only victor.

It is spring 1792 and England is enjoying a troubled peace, with her old enemy France still in the grip of the Terror. In harbours and estuaries around the country, the fleet has been left to rot, and thousands of officers and seamen have been thrown unwanted on the beach. Even a frigate captain as famous as Richard Bolitho is forced to swallow his pride and visit the Admiralty daily to plead for a ship. As the clouds of war begin to rise once more over the Channel, he has no choice but to accept an appointment to the Nore, and the thankless task of recruiting for the fleet. For Bolitho, still suffering the after-affects of a fever caught in the Great South Sea, and haunted by the death there of the woman he had loved, even so humble a command is a welcome distraction. With his small flotilla of three topsail cutters he sets out to search the coast for seamen who have fled the harsh discipline of His Majesty's Navy for the more tempting rewards of smuggling. As he is soon to discover, his opponents are no ordinary free traders, but the most brutal gang of smugglers England has known, the Brotherhood – a gang with men of influence behind them and a secret, sinister trade in human misery. Treason is never far distant, murder commonplace, and when a King's ransom is in peril, Bolitho is ordered to proceed 'with all despatch' to recover it. Trapped by the treachery and cunning of an old adversary, and under enemy fire, he needs all the loyalty and courage of his three gallant cutters if he is to fulfil his mission.
