Reception
The book has received reviews from publications including Booklist, Publishers Weekly, and Kirkus Reviews.

Publishers Weekly stated the book was a "comprehensive, sometimes critical and often dry history" with "all aspects of the agency's work are covered extensively: recruiting, training, intelligence gathering, the often-tense relationship between the agency and the people it tries to protect" and that it is "a worthwhile book for assassination buffs and those with an interest in the inner workings of government".

Kirkus Reviews stated "In mining the relationship between the agency and presidential families it has served, Melanson provides some fascinating insights" and that the book as a whole was "somewhat plodding, but with gems along the path".
