"It is a thriller. . . but at the same time it is a cool, sane study of one of the long and important chapters of American crime."—Stanley Walker, New York Herald Tribune Lively Arts
"For the squeamish, this book is not bedtime reading. . . . Yet it is less morbid, better documented, and more interpretively written than earlier galleries of western outlaws. Mr. Wellman tries to leave out the myths. . . . The outcome is a book of historical value in a field that too long has been left to legend and folklore."—Wayne Gard, New York Times Book Review
