the only thing I do not understand ( which is mentioned in CAL book ) is that he said if he had realised the type of gun and the number of shots he would have been suspicious. ( so if it had been a shot gun he would not have been? ) But he did not seem to have a clue until Jeremy was arrested - but surely he knew the details of the shooting before then? Mind you the family seemed to keep him out of their suspicions , so perhaps it did just not register .
