One of the first books published in the series is Douglas Valentine's invaluable, in-depth history of one of America's most egregious counterinsurgency, torture and assassination programs, as described in his 1990 book The Phoenix Program: America's Use of Terror in Vietnam.
The book is intricately and densely written, yet reads like a Rashomon-like detective story, as Valentine allows many of the actors involved speak for themselves. Never has such an in-depth look at a major CIA operation been written. You know who did what and when. The larger picture is not lost either, as, for instance, Valentine refers to earlier counter-terror programs that influenced Phoenix, such as the UK's counterinsurgency-terror program in Malaysia after World War II.
