The Pimlico Mystery or the Pimlico Poisoning Mystery is the name given to the circumstances surrounding the 1886 death of Thomas Edwin Bartlett, possibly at the hands of his wife, Adelaide Blanche Bartlett, in the Pimlico district of London. A fatal quantity of chloroform was found in Mr Bartlett's stomach, despite having not caused any damage to his throat or windpipe, and no evidence of how it got there. Adelaide Bartlett was tried for her husband's murder and was acquitted. By the jury's own statement in court Mrs Bartlett's acquittal was partly secured because the prosecution could not prove how Mrs Bartlett could have committed the crime.
