If this is to be believed, then it appears that American intelligence may have known in 1967 about the drug pipeline Plinston benefited from two years later. If what Pearson says on this score is reliable, it is possible that having failed to get the Krays to take over the pipeline the American authorities left it up and running for future use, and it is the same drug conduit that Plinston later stumbled upon. That said, despite the paranoia that permeates the drug subculture, I'm unaware of anyone from the circles around Plinston and Thompson who believes they were set up to be
the quickest, safest way for the twins to become millionaires. As a start Cooper suggested setting up a flat in Belgrave Square as a clearing house for wealthy addicts and their pushers. Cooper got as far as renting the flat when Ronnie said he wasn't interested. Other rackets they discussed were large-scale gold smuggling, further currency deals, a take-over of an existing marijuana racket carried on through the diplomatic immunity of some Pakistani diplomats and the traffic in illegal Asian immigrants from Belgium. And each time it was Reggie’s caution that prevented Ronnie from becoming involved... 
busted in Lorrach. It is nonetheless curious that on 18 July 1968 when Alan Bruce Cooper appeared as a Crown witness at Bow Street Magistrates Court against the Kray brothers, he should deny he'd given the police information about Victor James Kapur and Harry Nathan, claiming: "I discovered my father-in-law (Nathan) was a runner for the LSD Kapur was manufacturing when it came out in the papers." Nathan was busted in his son-in-law's car, and the police found Cooper at Nathan's flat when they went to search it immediately after this arrest. 
Under oath on the same day of the Kray hearing, Cooper also denied that he'd planned to kidnap the Pope and hold him to ransom, and repeated his claims that he'd had a two year involvement with American intelligence, stating that the Krays' lawyers could check this by applying to the European office of that service. This was reported in The Times of 19 July 1968. Top cop Leonard Read in his autobiography Nipper Read: The Man Who Nicked The Krays provides a more complex take on Cooper's relations with the British police than the one given at Bow Street Magistrates Court. Read does, however, assert that the
While travelling in the Middle East in 1967, Graham Plinston met Salim Hraoui  through a third party. Among other things Hraoui wholesaled hash and the two men decided they could do business. The Lebanese connection Plinston established in this casual fashion
year-old boyfriend of the time, John Sherwood Pendry. Their chemist Victor James Kapur, who was just a year younger than Detta, was given a nine-year stretch at the Criminal Court at the end of May 1968 for manufacturing LSD. Amazingly, Whybrow got off with two years probation. A 54 year-old antique dealer Harry Nathan of Chelsea copped the main blame for overseeing the distribution of the acid and was jailed for seven years; my view is that Nathan was a very minor player and Detta was the only individual who played a key role in the acid distribution to be arrested. A 31 year-old dispenser Mohammed Hassan Ally who assisted Kapur got 21 months. The authorities claimed the LSD involved had a black market value of a quarter of a million pounds. But prior to this bust taking place, another important drug connection opened up for the circles to which Detta and my mother belonged.
There may be some mythologising going on here, while Detta does seem to have suggested to the john he manufacture acid for her friends to deal, the lure of easy money was probably enough to convince him it was a good idea. That said, when the cops raided the two acid laboratories set up by Victor James Kapur, they also recovered a huge stash of photographic negatives showing him having sex with Whybrow and various other women; agreeing to pose for these shots could have been the means by which Whybrow's circle got the chemist to commit to manufacturing LSD for them. Terry Taylor informed me recently that at first he thought Detta had gone crazy when she told him she had a john who'd make acid for her. Street sources say the acid was extremely pure and potent; the English equivalent of the legendary Orange Sunshine.
In November 1967, after a series of police raids across north and west London aimed at smashing an LSD manufacturing and distribution operation, Detta Whybrow then aged 39 was one of ultimately nine individuals hauled up before the beak at Bow Street Magistrates’s Court over drug offences. Hauled in alongside Detta was her 29
