About the Author

John Book WebsiteJohn F. Gallagher served over thirty years on the Boston Police Department and retired at the rank of superintendent. As a command staff member, he was the department’s chief of detectives.

His interest in history and genealogy and his background in criminal investigation motivated him to write about these century-old murders on the South Shore. John and his wife, Jeanne, live in Hanover, Massachusetts.

Gallagher published his third book, A Monument to Her Grief: The Sturtevant Murders of Halifax, Massachusetts, in December 2016. He will speak about his latest book and his first two books, Arsenic in Assinippi and Murder on Broadway, at upcoming local author events.
