We are made to believe that these calls were made on the night of the murders.
1 Ralph to Jeremy.
2 Jeremy to Julie.
3 Jeremy to Ralph.
4 Jeremy to the police [unanswered]
5 Jeremy to police [answered]
Here is my problem about this. If my father had phoned me about a nutty daughter going berserk I would have sped to the farm. Jeremy chose to call Julie instead. he then said to the police " Christ you took a long time".
Jeremy was certainly in no hurry, or he would have phoned the police first.
IMHO he would/ should have dialled 999, but chose to call a local station.
