"Nowhere Near Worth it's Weight in Gold".
As one would expect in the process of a 'Police Investigation', the 'Clues' or other matters of interest are thoroughly examined by various members of the 'Investigative Team', each one assigned to the task of gleaning whatever positive facts they can from the information they have at their disposal.
One such 'Member' took it upon himself to look more closely at what might have been contained in the 'Box' which was given to 'Chris' for delivery, glancing through the statements made by 'Chris', his attention was drawn to the 'Parcel' which 'Chris' had first been sent to collect and he decided to concentrate his efforts on THAT point, he researched the notes taken when 'Chris' was interviewed and found that the question of size and weight of the 'Parcel' had been discussed, it was not a very large one and the weight was estimated to be about '2 Kgs' and something about the size of a good quality 'Shirt Box', it was a 'Hard Parcel' and might well be exactly that which is indicated here.
His attention was then drawn to the notes taken during the interview with the 'Six' financial 'Backers', he knew from the details that they had given, that each of them had 'Invested' 'Fifty Thousand Pounds' in 'Cash' and he began to research the probable 'Weight' of the 'Three Hundred Thousand Pounds' if it was made up of an assortment of circulated and uncirculated notes of different values, his calculations confirmed that the 'Box' which 'Chris' had taken for delivery was quite capable of containing a sum in excess of the money 'Invested' together with the money which (he assumed) was in the 'Parcel' collected by 'Chris'.
His next move was to discover whether or not the 'Serial Numbers' of any of the notes passed over in the transactions were available, he was disappointed to discover that they were not, in each case, the 'Backers' confirmed that the 'Cash' used was that which had passed among themselves whilst 'Dealing' with each other, the accumulation of such sums may well be part of the end product of years of such 'Deals' and would therefore be impossible to trace.
By adopting this train of thought, he was able to arrive at a very accurate assessment of just how the entire 'Deception' was set up, the 'Rabbi' was very foolish to have allowed himself to be so easily 'Tricked' into becoming party to such an obvious 'Scam' (if that is what it was) BUT, when 'Greed' preoccupies the mind, even the wisest and most careful are susceptible to it's influences, if it transpires that it WAS a 'Scam', then it was one which was performed with great skill.
Satisfied that his efforts were of some value in the 'Investigation', it was now his task to 'Link' his findings to those of the other 'Officers' in the hope that they may be connected to the 'Murder' inquiry, it MUST be assumed that his 'Theory' is correct (if it is not, there will be a re-think) in order that an overall picture of the events leading up to the 'Murder' might lead to the arrest of those responsible.
Without 'Positive Proof' of ANY substantial event thus far, the only route possible for the 'Police' is one which relies on the outcome of the 'Processes of Elimination' which attend every idea and supposition throughout the 'Investigation', almost like trying to make way through a thick 'Fog' whilst hoping that suddenly a 'Shaft of Light' will point the correct way.
Such is the 'Lot' of the 'Police Officer' and it is small wonder that some of them are such 'Nasty Gits', they exist in a world where they have to unravel the webs of 'Lies and Deception' throughout their working lives, sadly, the effects of such an existence, often renders them unable to associate with anyone outside of the 'Force' on a 'Social Level' and anyone who thinks they have a 'Friend' who is a 'Policeman', had best be on their best behaviour, (Unless he is a 'Crooked Cop' like MY mate 'Arthur') but I STILL wouldn't bet my life on his 'Friendship.
