Larry Arnold, author of "Ablaze!" and leading researcher into spontaneous human combustion, joins Linda Moulton Howe to investigate this mysterious phenomenon where human bodies apparently ignite without external heat sources. Arnold discusses the forensic evidence from authenticated SHC cases, including the extreme temperatures required to consume human tissue and bone while leaving surrounding materials completely undamaged. The conversation covers investigation methodology used to rule out conventional ignition sources and the consistent patterns observed across documented SHC cases worldwide over several centuries. Howe contributes her investigative journalism expertise to analyze the evidence and explore potential connections to other unexplained phenomena involving anomalous energy manifestations and human physiology. The discussion examines various theories about bioelectrical energy accumulation, quantum mechanical explanations, and possible external energy sources that might trigger these devastating combustion events. Arnold presents his most compelling cases and explains the forensic analysis techniques used to distinguish genuine SHC from conventional fire deaths caused by external ignition sources. The conversation explores whether spontaneous human combustion represents a natural but poorly understood human capability, a rare medical condition, or evidence of external forces affecting human physiology in extraordinary ways that science has yet to comprehend or acknowledge.
