This fifteenth Spider Shepherd thriller sees the terrorist codenamed Saladin act again for the first time in ten years, with one of the victims related to the acting head of MI5 who given the severity of the situation is quick to put Spider on the case. Spider must travel with the only person who can recognise Saladin - a psychologically damaged former Navy SEAL named Dean Martin - to the border between Pakistan and Afghanistan to stop Saladin once and for all.
