AP was left " holding the fort " at Goldhanger,a day or two after the tragedy in order to let Jeremy do any necessary running around that had to be done.
If there had been anything untoward within Jeremys' house during this time,I'm sure AP would have spotted it. Like the odd spot of blood,mud,heap of soiled clothes,anything that would have indicated or implicated Jeremy as having been responsible for a vicious confrontation.
Obviously nothing to report,and Jeremy couldn't have been bothered about leaving his home to the mercy of others. So nothing there to report in AE's notebook.
