Allow me to explain, When Jeremy was first spoken to too by DCI "Taff" Jones, and DS "Stan" Jones, at his cottage at 9 Head Street, Goldhanger, the police said that Jeremy told them that he called the police, (3:36am), after he called his girlfriend, (3:30am), Julie Mugford...
Later, when the nature of the investigation altered, at the beginning of September 1985, from SC/688/85, into SC/786/85, Jeremy was arrested, and spoken to, during interview by the police, who put it to him, that although he told the police originally, that he had spoken to Julie Mugford (3:30am) on the telephone before (3;36am) he had spoken to the police, that police records showed that he had in fact spoken to Julie, (3:30) after he had spoken to the police, (3:26am). In other words, they tried to disorientate him, which led to Jeremy responding by saying that the first version he had given to the police at his cottage, was the correct explanation...
They tried to disorientate him, by using references to two different times(3:30am and 3:15am) that Jeremy supposedly made the call to Julie on the morning of 7th August 1985, and by reference to two differently timed telephone calls received by the police, namely, 3:26am and 3:36am...
It would depend from a readers point of view, which time reference for the call to Julie you chose to rely upon, as opposed to the timing of the call made to the police, either Ralph's call timed at 3:26am, or Jeremy's own call timed at 3:36am, as to whether you chose to believe that Jeremy called Julie before or after the call to the police......
