Since it was possible for a specialist bt engineer to have examined the metering system back in the local substation which dealt with calls to and from white house farm, and because Essex police seized Jeremy's answer phone and five audio tapes for the purpose of determining whether there had been a call from white house farm to Jeremy's cottage, it must also follow, that by adopting the same technical analysis to the telephone metering associated with the phone line at white house farm toJeremy's cottage, it stands to reason that Essex police must have and did get confirmation one way or another, that there were two calls, one identifiable from the metering records associated with white house farm, and the other associated with the line at Jeremy's cottage, where one was an outgoing call, and the other an incoming call, both of identical length! Furthermore, that insofar as the metering system associated with Jeremy's cottage at Head Street, Goldhanger, the breakdown of the individual calls he had made to Julie Mugford', and then to PC West at Chelmsford police station would have been available to Essex police, if they had needed to go that / this far!
Anyway, you can believe what you want, I know what I was told, and there was no reason for either of these two bt engineers to tell me lies about it!
