April 1814. Napoleon is deposed and exiled after defeat by a resurgent allied collation. Saddled with huge war debts, the British government has no choice but to place many of its naval ships in reserve. Captain Sir Thomas Kydd is one of the lucky officers not to be put on half pay. Instead, in the realisation of his life's ambition, he is offered an admiral's flag, but the station is West Africa and with it comes anti-slavery operations set in fever-ridden swamps. Despite the obvious dangers and hardships, Kydd readies for sea with his beloved Thunderer as his flagship. But before he can set sail comes the electrifying news - the tyrant has escaped from Elba and is marching on Paris, the citizens flocking to join him. Napoleon's invasion fleet is still in being and if the French navy declares for him they can sail from the ports now free of blockade and make the invasion of England a reality. What's more, the entire Channel Fleet has been stood down, its ships in various stages of repair. There's one man in active service who happens to be on the spot - Admiral Sir Thomas Kydd. With frantic haste he's appointed temporary commander-in-chief to sail with all the men-o'-war that can be scraped together to stand athwart the French. Waterloo is coming but before then Kydd must use all his legendary subterfuge and daring to save England from her peril. Admiral is the twenty seventh and last of the adventures of Captain Sir Thomas Kydd whose story began in the year 1793 and tells for the first time in fiction how a pressed man through his bravery and ingenuity progresses to the quarterdeck of his own ship, and here, in the final book of the series, the command of a fleet with an admiral's pennant.
