WHO'S WHO IN THE SECRET SERVICE: HISTORY'S MOST RENOWNED AGENTS (my fourth book) coming 9/1/18 ! A strong argument could be made that this one is my best book- widest appeal, most accessible, etc. Researchers will love quite a bit of the information (especially some of the appendices), while non-researchers will find much of interest here, as well. I thought my last book had some wider appeal, but THIS one REALLY does!
