Oh dear. You've started this again, haven't you..
As usual, I sense that Steve and Adam are rather missing the point.
Everybody accepts that, sometimes, in order to convict a serious criminal the police may have to obtain the co-operation of a lesser criminal, including accomplices.
If Jeremy is guilty and if that is what happened here between the police and Julie, then personally I don't necessarily object to an arrangement of that kind in order to convict the primary offender. I'm also sure there are ways of rationalising it: she was sucked into the situation, she was not present at the shootings, etc.
However, the point here is that until this thread, both you and Adam had denied it was a Faustian pact and instead defended Julie as if she had no culpability and was an innocent person. In reality she is very probably not. The early morning phone call suggests as much, but we can put that to one side. The point is that Julie was being held up by you and Adam as some sort of heroine.
Yet in this thread, Adam now quite clearly concedes that indeed it was a Faustian pact between the police and Julie.
I know Steve doesn't like to hear any adverse discussion about his unrequited love, but I am hardly the first person to consider the possibility that Julie was Jeremy's accomplice. It has been discussed on here before many times before, and without your unwelcome interruptions from Steve. I suggest that, for his own good, Steve goes back to playing at Cluedo with Myster. I hear that Myster is missing a Reverend Green. He's already got a Plum - Real Justice fits that role very well.
