david had actually met hamid shah several times in his travels , when hamid was a good guy , but now he was the right hand man of osama bin laden , with a lucrative side line in killing and maiming british soldiers with his own versions of road side ieds ( improvised explosive devices ) , so he was now a bad guy , a very very bad guy , so david was obviously the person of choice to be in kabul , the capital of afghanistan , co-ordinating the hunt for him , and was on hand when they heard a rumour that shah was to have an important high level meeting in the compound of a prominent warlord in 4 days time .
