Don Pendleton's Mack Bolan Executioner
They have gone through lots of fine authors in the Executioner series, Mike Newton, Raymond Obstfeld, Stephen Mertz, Peter Leslie, Dan Schmidt, Mel Odom, David Robbins & Keith DeCandido to name a few. I've always appreciated they give credit to the writers on the publishing information page.
Don Pendleton was a great man. He will be missed, but always remembered for Mack Bolan and the Executioner family.
Thank you for your time.
