Onassis died in March 1975, and Caroline returned to Skorpios for his funeral. A few days later she and her mother and brother attended the presentation by French president Valéry Giscard d'Estaing of the Legion of Honor award to her aunt, Eunice Kennedy Shriver. Later that year, Caroline was visiting London to complete a year-long art course at the Sotheby's auction house, when an IRA car bomb placed under the car of her hosts, Conservative MP Sir Hugh Fraser and his wife, Antonia, exploded shortly before she and the Frasers were due to leave for their daily drive to Sotheby's. Caroline had not yet left the house, but a neighbor, oncologist Professor Gordon Hamilton Fairley, was passing by when he was walking his dog and was killed by the explosion.
