In this sequel to “Pride Runs Deep” Cooke’s hero Jack Tremain returns to the Pacific in command of the submarine Whitefin. He defies orders to hunt – Ahab-like – the Japanese destroyer that sunk his earlier command. It’s a solid historical techno-thriller but unfortunately the character development that distinguished its predecessor takes a back seat to somewhat implausible action as Tremain finds himself fighting ashore with guerrillas in the Philippines.
