Pre-order our newest Forensic Science Publication: Wigmore on Carbon Monoxide

Wigmore on Carbon Monoxide delivers a captivating and in-depth look at the historical, scientific, and legal dimensions of carbon monoxide — humanity’s silent and ancient killer. This odorless, invisible, and non-irritating gas has claimed lives since the earliest use of fire, with mysterious deaths once blamed on demons or witchcraft due to a lack of understanding about ventilation and combustion.

Even in the modern age, carbon monoxide poisoning continues to pose a serious risk. It can result from everyday items like gas stoves, water heaters, charcoal grills, tent heaters, diesel-powered tools, and even indoor Zamboni use. In this comprehensive and well-structured work, forensic toxicologist James G. Wigmore draws from over 600 scientific sources to present the dangers of CO in a clear, accessible way.

Designed for legal, scientific, and investigative professionals — including lawyers, judges, medical examiners, coroners, forensic experts, and students — Wigmore on Carbon Monoxide is an essential reference for anyone involved in unexplained deaths or medicolegal investigations involving this deadly gas.
