George Madoc had commanded an RAF Air-Sea Rescue boat ferrying secret agents between the south coast and occupied France. One night in April 1944 an operation to bring back a French agent went terribly wrong, and when George finally made it home two months later, he was unable to speak about what had happened. Hi son, Iain, is finally given a clue to unlocking the mystery of what so traumatised his father that he turned away from his own son. The wreck of his father's boat has been found near the Breton village of St Cyriac, and with it, perhaps, the key to unlocking George Madoc's memories. Desperate to understand, Iain goes to St Cyriac determined to discover the truth. But St Cyriac will not give up its secrets easily. For some people the past is still dangerously alive, and Iain soon finds that his own family may have to pay the price of uncovering it.
