The Rigger: Operating with the SASPaperback, 19 August 2015

For most people, climbing a ladder to clear the gutters is a challenge. Jack Williams and his colleagues in the specialist signals unit supporting the SAS in Northern Ireland had to climb towers and maintain vital communications - often in full view and under fire from terrorists.

This is the gripping insider story of the tension, fear and comradeship of these specialists, who needed more than just a head for heights.

Written in a racey popular style ''The Rigger'' is bound to thrill for its insider action. The author witnesses many operations, some successful, others tragically costly.
