New York-based shipping magnate Phillip Carlton is found dead on the beach at a Christmas party, apparently having shot himself after recording what seems a goodbye video. London cab driver Colin Babcock reports having received a Christmas card from Saint Marie claiming Carlton was murdered. Commissioner Patterson orders Neville Parker, who was about to return home to Manchester for Christmas, to investigate the family. The Commissioner also recruits retired officer Dwayne Myers to assist as Florence Cassell is away spending time with her family. Suspects include Carlton's wife, her lover, Phillip's first wife, Carlton's daughter, and his poorly rewarded long term employee Bruce Garrett. Surprisingly, Colin Babcock arrives in Saint Marie with the Christmas card and an attempt on his life fails while he sleeps at Neville's. On a video call to Florence, Neville asks her out, but the computer screen freezes so he cannot see her reaction. Dwayne and Marlon are on a wild goose chase after suspected witness Zelda Moncrief on Guadeloupe. It turns out Philips's family secrets are the key to the case and his fortune.
