The weird death of Gilbert Bogle

Dr Gilbert Bogle’s death - along with Margaret Chandler - was about sex and drugs and is still a mystery 60 years on.
It was New Year’s Day when his body was spotted near a golf course in Sydney by two men out foraging for golf balls.
Gilbert was on his back, with his clothes laid out on top of him along with a piece of carpet, weirdly neat.
Not far from him was Margaret Chandler whose floral dress was disordered but with three pieces of cardboard covering her.
They had met at a New Year’s Eve party run by Ken Nash.   Gilbert had left his wife at home and Margaret had come with her husband Geoffrey.   The pair had an understanding about sleeping with other people.  Indeed, Geoffrey left the party to see his mistress.
Gilbert and Margaret left the party together and it was the last time they were seen until their bodies were discovered.
Gilbert Stanely Bogle was born January 5, 1924 in Whanganui to Archibald and Bertha.  He attended Whanganui Collegiate, then on to Victoria University.  
Like many men of the right age, he was eligible for war service at the start of World War two but he was allowed to continue working at his laboratory.  
In 1947, he went to England as a Rhodes Scholar and studied at Oxford where he got his doctorate in physics and three years later married Vivienne Mary Rich.  
Back in New Zealand he lectured at the University of Otago but quickly he outgrew it and in 1956 went to the Commonwealth Scientific and Industrial Research Organization's division of physics at the National Standards Laboratory, Sydney.   He worked with cryogenics and maser (microwave amplification by stimulated emission of radiation) technology.
  And by 1962 he was considered by his boss to be the most brilliant of the staff.   
Then at a Christmas party he met Margaret Chandler, the wife of one of his colleagues. 
They met again at a New Year’s Eve party and, encouraged by Margaret’s husband, he offered her a ride home.  And sometimes before 6am on New Year’s day 1963 they both died on the eastern bank of the Lane Cove River, near Fullers Bridge, Chatswood.
How they had died was a mystery and it was generally believed it was poison or a type of drug overdose.  But what?  Tests revealed nothing toxic.
Margaret’s husband Geoffrey was a suspect as was another lover of Bogle’s, librarian Margaret Fowler.  
Conspiracy theories also abounded, including that Bogle was about to disclose Australian Atomic Energy Commission secrets that led to an assassination.  
But in 2006 a new theory came to light after a documentary maker uncovered evidence that the nearby polluted river may have let out an eruption of hydrogen sulphide gas.  
That doesn’t explain how they came to be covered up.
Margaret Chandler was cremated and Bogle was buried at the Macquarie Park  Cemetery and because no samples were kept, no tests can now be done with today’s advancements.
Unless someone comes forward it will likely never be solved.
