1976, December 29: Isleworth Woman’s Fiery Death
On Decmber 29, 1976, a 32-year-old woman in Isleworth, Middlesex, England, was found burned in her living room where a small fire had occurred. Fire and smoke was not detected outside.
This is the first listing of this incident in Anomalies, and therefore will require more research to confirm it. This is especially true because the above comes from Jenny Randles and Peter Hough's 1992 book, Spontaneous Human Combustion; this book gives almost no sources for the accounts it relates, most often attributing them to "Author's own investigation" and "Historical archives traced and researched"... which essentially means "Just trust us." In this case, the above is attributed to Fortean Times magazine, but we are not told a date or issue number. For this reason, this account is marked as both "Unreliable" and "Investigate;" I will add new information as I get a chance to dig further.
Given the details above, this account does not sound supernatural; we'll see what I find later.
