Author and former Marine Elliot Ackerman’s latest tale is about an ex-CIA Ground Branch operator who goes by his call sign, “Skwerl” and a former Afghan special ops pilot who goes by the name “Big Cheese” so you’re probably already getting a good picture of Ackerman’s latest novel Sheepdogs, which follows Skwerl and Cheese on a globe-trotting adventure from Uganda to Marseille. Cipher Brief CEO & Publisher Suzanne Kelly welcomed Ackerman to the Cover Stories Studio to talk about missing handlers, hidden cargo and shadow war.
