Indeed, there is reason to believe that if Mr Chohan had not met certain people "at school" - in jail - he, his wife, mother-in-law and children would be alive today. But their bungalow in Heston, once filled with the sounds of family life, is now an eerily silent crime scene. A baby's feeding bottle lay on the floor, the washing machine was filled with newly-laundered clothes and a treasured model of Thomas the Tank Engine was among toys strewn across the living room when the police went in. The Asian community in west London was shocked by the family's disappearance. But in business circles there was a sense that Mr Chohan - who was thought to have been courting disaster - had finally run out of luck.
