The Brighton coroner, David Black, ruled the death accidental. It was later confirmed that this was the only death caused by Edmunds. Edmunds increased her poisoning campaign, and began sending parcels of chocolates to prominent persons, including Mrs Beard, who again became violently ill. By this time, the police had connected the poisonings with the chocolates. Edmunds sent parcels to herself, claiming that she, too, was a victim of the poisoner, in the hope that this would deflect suspicion from her and on to Maynard. At this point, Dr Beard informed the police of his suspicions, which resulted in Edmunds being arrested and charged with the attempted murder of Mrs Beard and the murder of Sidney Barker. After committal hearings, it was decided to move the case from Lewes to the Old Bailey. During Edmunds's trial, which began in January 1872, her mother testified that both sides of their family had a history of mental illness. Dr Beard claimed that he and Edmunds never had a sexual relationship, but that instead it was merely a series of letters sent by her to him, and mild flirtations. Edmunds was sentenced to death, but this was commuted to life imprisonment due to her mental state. She spent the rest of her life in Broadmoor Criminal Lunatic Asylum, dying there in 1907. The 1939 novel "The Black Spectacles" by John Dickson Carr is based on the Edmunds case. "The Great Chocolate Murders", by John Fletcher, is a drama based on the events of the case, first broadcast by the BBC on Saturday 4 March 2006. It features Sîan Thomas, Chris Donnelly, Jennifer Hill, Dorien Thomas and Brendan Charleson, and was directed by Kate McAll. The case formed the basis of a puppet show, "The Sorrowful Tale of Sleeping Sydney", by Daisy Jordan, which she performed at the Theatre Royal, Brighton in August 2017 (and again in October of that year, as part of the theatre's Out of Hours season. It was co-written and directed by Ulysses Black, with music by Kate Daisy Grant, featuring violin and saw playing by Nick Pynn.
