diaries appear to substantiate his claims — at least from his early forties onwards. He lived alone all his adult life and had few close companions apart from his mother, and no significant romantic relationships. His diaries contain references to unconsummated or barely consummated homosexual dalliances, which he describes as "traditional matters" or "tradiola". He befriended gay playwright Joe Orton, who wrote the role of Inspector Truscott in Loot (1965) for him. Williams went on holidays to Morocco with Orton and his lover, Kenneth Halliwell. Other close friends included Stanley Baxter, Gordon Jackson and his wife Rona Anderson, Sheila Hancock, and Maggie Smith and her playwright husband, Beverley Cross. Williams was also fond of fellow Carry On regulars Barbara Windsor, Bernard Bresslaw, Peter Butterworth, Kenneth Connor, Hattie Jacques and Joan Sims. From the mid-1950s, Williams lived in a succession of small rented flats in central London. After his father died, his mother Louisa lived near him, and then in the flat next to his. His last home was a flat on Osnaburgh Street, Bloomsbury (since demolished). Williams rarely revealed details of his private life although, in two half-hour documentary programmes in 1977 on BBC Radio London entitled Carry On Kenneth, he spoke openly to Owen Spencer-Thomas about his loneliness, despondency and sense of underachievement. He died on 15 April 1988 in his flat. His last words, recorded in his diary, were "Oh, what's the bloody point?" and the cause of death was an overdose of barbiturates. An inquest recorded an open verdict, because it was not possible to establish whether his death was suicide or an accident. His diaries reveal that he had often had suicidal thoughts, and some of his earliest diaries record periodic feelings that there was no point in living. His authorised biography argues that Williams did not take his own life but died of an accidental overdose. The actor had doubled his dosage of antacid without discussing it with his doctor. That, combined with the mixture of medication, is the widely accepted cause of death. He had a stock of painkilling tablets and it is argued that he would have taken more of them if he had been intending suicide. He was cremated at East Finchley Cemetery, and his ashes were scattered in the memorial gardens. Williams left an estate worth just under £540,000 ().
