Finally, 'CAVEMAN' from ESSEX UNIV with his 'clue' - as given to ALLISON STONIER at ESSEX UNIV circa 1984:

KV told her about how he and his mates had put BICARBONATE OF SODA between pieces of white bread and then fed them to the ducks upon the campus lakes.

The ducks had then had to swallow too much water and then exploded...STONIER exploded in anger...how cruel...how could you...and then denied the possibility...they couldn't have exploded...he assured her that they had.

KV appeared to be talking about something else though...something symbolic.

BY-CAR-BON CULT - ATE/8/CIA 'TRUE SODA'

i then thought about the DUCKS as in DUKES of the ill cult...and how throughout history...particularly during the TUDOR period...some dukes were as powerful as kings/queens...if not more so...the DUKE OF ANJOU...PRINCE OF ORANGE...DUKE OF NORMANDY...and there lay a clue to something...COLLIE became interested in the history...
