Wallace provides an overview of the chemical analysis of firearms, ammunition, and gunshot residue, with discussion of chemical aspects, protocols, methodology, and various laboratory tests, with brief discussion of history. He focuses on the detection of residue on a suspect's skin and clothing. The book is meant for use in forensic laboratories and by forensic chemists with little knowledge of firearms. Along with other sources, the book is based on statistics gathered at the Northern Ireland Forensic Science Laboratory during the country's years of violence, of which Wallace, a retired UK forensic scientist, was associated.
