Spontaneous human combustion (SHC) — the alleged burning of a human body without an apparent external source of ignition — has been reported and debated for over 300 years. The earliest well-documented case is often cited as that of Countess Cornelia di Bandi of Cesena, Italy, who was found reduced to a pile of ash, her legs, and three fingers in her bedroom in 1731, with the rest of the room showing minimal fire damage. Charles Dickens featured SHC in 'Bleak House' (1853), and the phenomenon has maintained a persistent presence in both popular culture and forensic science. Approximately 200 cases have been documented since the 17th century. They share consistent features: the body is severely or completely burned while nearby combustible objects are undamaged; the fire seems to originate within the body rather than from an external source; extremities like hands and feet often survive; and a greasy residue coats nearby walls and ceilings. The dominant scientific explanation is the 'wick effect' — in which an external ignition source (such as a cigarette) ignites clothing, and the body's own fat acts as fuel, with the clothing serving as a wick, producing a slow, sustained burn. However, critics note that the wick effect has been difficult to reproduce at the level of destruction observed in classic SHC cases.
