Togo Yashimoto, a ruthless disciplinarian steeped in the samurai tradition, is captain of the Japanese submarine I-357. John Barratt, captain of HMS Restless, is haunted by his wife’s death while a prisoner of the Japanese in Changi Jail. Two very different men whose destinies are linked in the deadly game of hide and seek they play out among the islands and atolls of the Mozambique coast.
Damaged while attacking an American freighter, Yashimoto makes for the coast to carry out repairs and to hide. HMS Restless rescues the only surviving crew member of the Fort Nebraska, and on the strength of his report, Barratt sets out after the submarine.
