Cruising somewhere off Saigon is the world's largest and most dangerous submarine - the French Soufrière. A rich prize for the enemy, the British navy must capture her for themselves before she is used against them.
For Commander Robert Ainslie, it represents the greatest challenge of his career. He must take the foreign submarine and use her against the enemy in the defence of Singapore . . .
A thrilling tale of naval warfare from Douglas Reeman, the all-time bestselling master of naval fiction, who served with the Royal Navy on convoy duty in the Atlantic, the Arctic and the North Sea. He has written dozens of naval books under his own name and the pseudonym Alexander Kent, including the famous Richard Bolitho books set during the Napoleonic Wars.
