Silent Service

One submarine. Forty-eight men. Eighty-two years of silence.In March 1944, HMS Stalwart vanished on patrol off Norway. That is what the Navy told the families.In October 2026, Lieutenant Rhona Gair and her Royal Navy dive team find her intact on the seabed thirty miles west of Orkney, hatches sealed, exactly where she should never have been.On the first dive, something knocks on the inside of the hull. Clean naval Morse: HOW LONG UNTIL RESCUE. AIR FOUL. 31 ALIVE.It happens again. And again. Every hour, on the hour, the dead boat sends her distress call, then waits five minutes for an answer. Leading Diver Sam Pickering recognises the hand on the key. It belongs to his great-grandfather.Then a commander arrives from Northwood with one order: whatever it is, you do not answer it.As a winter storm closes in, Rhona follows the trail to a hundred-and-one-year-old man in a Kirkwall care home who has kept a secret since he was nineteen, and to a pencilled signal form that should never have survived. Stalwart's crew were not lost. They were heard. Someone decided not to reply.Now the Navy wants her sealed under concrete. But the crew are still asking the same question, and somebody owes them the answer.The Silent Service is a haunting ghost story of duty, secrecy and the debt we owe the dead, for readers of Michelle Paver's Dark Matter, Dan Simmons' The Terror and Das Boot.
