Alfred de Marigny

Several books have been written about the case, including one by de Marigny himself. Many theories have been advanced, including suspected mob involvement, but the Nassau newspaper editor John Marquis insisted in his book Blood and Fire (published in 2005) that the murder was strictly a local affair, planned by wealthy Nassau whites to prevent Oakes from moving his money to Mexico. It implicated Sir Harold Christie in the plot and blamed the Duke of Windsor for orchestrating a cover-up by importing two crooked Miami detectives to conduct the investigation.

The jury acquitted de Marigny of the murder charge but gave a recommendation that he was an "undesirable alien" and should be removed from the island. The deportation recommendation is rumored to have been influenced by his unpopularity among the ruling class on the island. (The Duke of Windsor had described de Marigny as "an unscrupulous adventurer [with] an evil reputation for immoral conduct with young girls".) Following his deportation, the de Marignys settled in Cuba before separating in 1949.

De Marigny went to Canada toward the end of World War II and enlisted in the Canadian Army in July 1945. He lived in Quebec for three years before being deported. He spent various amounts of time in the United States, Jamaica, Haiti and the US again before finally moving to Central America.

De Marigny married Sir Harry Oakes's daughter, Nancy, the day after her 18th birthday. It was de Marigny's third marriage; both of the first two were also to wealthy women who broke off those relationships soon after marriage. When Sir Harry was murdered on 7 July 1943, de Marigny was the main suspect and was arrested shortly after. At his trial, detectives which the Duke of Windsor, then Governor of the Bahamas, had brought in from Miami claimed to have found de Marigny's fingerprint near the bed of Sir Harry Oakes. The defense argued that the fingerprint had been lifted and placed in the bedroom. Nancy Oakes supported her husband throughout the trial and testified on his behalf. There is a theory that Sir Harry was murdered because he was going to reveal the existence of a scheme involving the Duke of Windsor and Nazi German money being laundered through Mexico. Implicated in this treasonous venture, as well as in the murder, are Harold Christie and his brother Frank. It is typical of the good burghers of Nassau, the very same people whom de Marigny despised, that any scandal involving "one of their own" is swept under the carpet.

Alfred de Marigny (29 March 1910 – 28 January 1998) was a French Mauritian acquitted of the murder of his father-in-law, Sir Harry Oakes.

Marie Alfred Fouquereaux de Marigny, whose real name was Alfred Fouquereaux, "de Marigny" being his mother's name, was born on 29 March 1910, in Mauritius to a well-off French family. He let people address him as Count, but it is clear that he was not part of a noble family. De Marigny assumed the French title of count from his mother's side of the family.
