In 1926, she developed from clairvoyant to physical medium by offering séances in which she claimed to be able to permit the spirits of recently deceased persons to materialise, by emitting ectoplasm from her mouth.

"The London Spiritualist Alliance had fifty sittings with her between October 1930 and June 1931; for these sittings she was stripped, searched and dressed in 'seance garments'. Two interim reports in ''Light'' were favorable, a third found indications of fraud. Pieces of 'ectoplasm' found from time to time differed in composition. Two early specimens consisted of paper or cloth mixed with something like white of egg. Two others were pads of surgical gauze soaked in 'a resinous fluid'; yet another consisted of layers of lavatory paper stuck together. The most usual material for 'ectoplasm' however, seemed to be butter muslin or cheesecloth, probably swallowed and regurgitated. Distressing choking noises were sometimes heard from within the cabinet; and it was interesting that when she was persuaded to swallow a tablet of methylene blue before one of the seances at the London Spiritualist Alliance, no ectoplasm whatsoever appeared."] One of Duncan's tricks was to swallow and regurgitate some of her ectoplasm, and she was persuaded to swallow a tablet of methylene blue

(1966). ''Spiritualism: A Critical Survey''. Aquarian Press. pp. 137–144]
Harry Price's investigation
A piece of ectoplasm from one of Duncan's early séances was obtained and secured in a bottle of distilled water. It was given to the psychical researcher Harry Price

mixed with chemicals. Price later duplicated Duncan's ectoplasm with similar substances.[Tabori, Paul. (1961). ''The Art of Folly''. Prentice-Hall International, Inc. pp. 180–182. ]
In 1931, Price paid Duncan £50 (almost £4,300 in 2024) to conduct a number of test séances. She was suspected of swallowing cheesecloth, which was then regurgitated as "ectoplasm". Price had proven through analysis of a sample of ectoplasm produced by Duncan that it was made of cheesecloth. She reacted violently at attempts to X-ray her, running from the laboratory and making a scene in the street, where her husband had to restrain her, destroying the test's controlled nature. According to Price, in a report of the mediumship of Duncan:
In his report, Price published photographs of Duncan in his laboratory that revealed fake ectoplasm made from cheesecloth, rubber gloves and cut-out heads from magazine covers which she pretended to her audiences were spirits. Psychologist William McDougall, who attended two of the séances, pronounced her "whole performance fraudulent" in an appendix to the report.
Following Price's report, Duncan's former maid Mary McGinlay confessed in detail to having aided Duncan in her mediumship tricks, and Duncan's husband admitted that the ectoplasm materialisations were the result of regurgitation.

started to take an interest in her activities. Two lieutenants were among her audience at a séance on 14 January 1944. One of these was a Lieutenant Worth, who was not impressed as a white cloth figure had appeared behind the curtains claiming to be his aunt, but he had no deceased aunt. In the same sitting, another figure appeared claiming to be his sister, but Worth replied his sister was alive and well. Worth was disgusted by the séance and reported it to the police. This was followed up on 19 January, when undercover policemen arrested her at another séance as a white-shrouded manifestation

had been indiscreet to Professor Michael Postan of the Ministry of Economic Warfare. Postan said that he believed he had been told officially, and was not arrested.
Duncan was found to be in possession of a mocked-up HMS ''Barham'' cap-tally. This apparently related to an alleged manifestation of the spirit of a dead sailor on HMS ''Barham'', although Duncan apparently did not know that after 1939 sailors' cap-tallies carried only 'H.M.S.' and did not identify their ship. She was initially arrested under section 4 of the Vagrancy Act 1824, a minor offence tried by magistrates. The authorities regarded the case as more serious, and eventually discovered section 4 of the Witchcraft Act 1735, covering fraudulent "spiritual" activity, which was triable before a jury. Charged alongside her for conspiracy to contravene this Act were Ernest and Elizabeth Homer, who operated the Psychic centre in Portsmouth, and Frances Brown, who was Duncan's agent and went with her to set up séances. There were seven counts, two of conspiracy to contravene the Witchcraft Act, two of obtaining money by false pretences, and three of the common law offence of public mischief. The prosecution may be explained by the mood of suspicion prevailing at the time: the authorities were afraid that she could continue to reveal classified information, whatever her source was. There were also concerns that she was exploiting the recently bereaved, as the Recorder noted when passing sentence.

Repeal of the Witchcraft Act
In 1944, Duncan was one of the last people convicted under the Witchcraft Act 1735 ( 9 Geo. 2 c. 5), which made falsely claiming to procure spirits a crime. She was sentenced to nine months' imprisonment. When convicted, she cried out "I have done nothing; is there a God?".
On her release in 1945, Duncan promised to stop conducting séances, but she was arrested during another one in 1956. She died at her home in Edinburgh a short time later.[ Duncan's trial almost certainly contributed to the repeal of the Witchcraft Act 1735, which was contained in the Fraudulent Mediums Act 1951 ( 14 & 15 Geo. 6. c. 33) promoted by Walter Monslow, Labour Member of Parliament for ]Barrow-in-Furness

have written, it is unlikely that there was anything unusual about Duncan's death, nor was it caused by the police disturbing her "trance." Duncan's medical records indicated that she had a long history of poor health, and as early as 1944 was described as an obese woman who could move only slowly as she suffered from heart trouble.
Legacy
After her death, Duncan was widely cited as an example of a fraudulent medium. However, some spiritualists continued to defend her. According to Jenny Hazelgrove,
Psychical researcher Simeon Edmunds also noted that spiritualists had a history of ignoring the evidence of fraud in the Duncan case. He criticized the spiritualist press such as '' Psychic News'' for biased reporting and distorting facts. Science writer Mary Roach, in her book '' Spook: Science Tackles the Afterlife'' (2007), favorably mentioned Price's methods in debunking Duncan as a fraudulent medium.
In 2009, a heavy metal band, Seventh Son, recorded and released a song, "The Last Witch in England", depicting Duncan's life and her claims about the sinking of HMS ''Barham''.
