A new book reveals a surprising incident at Jacqueline Kennedy Onassis's Cape Cod home. "White House by the Sea" by Kate Storey recounts the discovery of marijuana growing in the former first lady's garden around 1975. Kennedy's assistant, Kathy McKeon, noticed suspicious activity and, with former police chief Jack Dempsey, investigated, uncovering the unexpected plants.

Upon learning of the situation, Kennedy was reportedly shocked, prioritizing discretion. She quickly consulted with Dempsey, who assured her the matter would be handled quietly. Dempsey and the Secret Service subsequently removed the plants. Neither of Kennedy Onassis's children were implicated.

"White House by the Sea" offers a glimpse into the Kennedy family's life at their Hyannis Port retreat. The book details how the former first lady, following the deaths of both President Kennedy and Aristotle Onassis, found solace at the Cape Cod estate, often hosting family and enjoying activities like sunbathing and painting. The book also touches upon other aspects of Onassis’ life at Hyannis Port.
