In the spring of 1939, life at Highfield, a twenty-two-room vacation home on nine hundred acres in Suffolk on Prince Edward Island, should prove idyllic. Michael Moreland, the superintendent of the manor, and Susan Moncrieff, the daughter of Sir Richard and Lady Richard Moncrieff, Highfield's owners, look forward to their wedding just a few months away. Susan and her mother have arrived on the island only recently, sent by Sir Richard from Clifton Manor, the Moncrieff family home in Suffolk, England. A retired rear admiral of the Royal Navy, Sir Richard serves as a senior SIS strategist in London, monitoring the growth of the Nazi war machine on the continent. Convinced that war is imminent, he purchased Highfield to provide for the safety of his wife and daughter. With two sons serving as officers in the Royal Navy, and certain that war is imminent, the family braces for what seems to be the inevitable. With German operatives newly detected on the island, and German U-boats already on patrol in the North Atlantic, how will the island and her people fare as they face the threat of the next war?
