Pimlico Mystery

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.

At the heart of the Pimlico Mystery is the odd relationship between a wealthy grocer, Mr. Thomas Edwin Bartlett (1845–1886), his younger French-born wife Adelaide Blanche de la Tremoille (born 1855), and the Reverend George Dyson, Adelaide's tutor and the couple's spiritual counselor and friend. Dyson was a Wesleyan minister, and (if the story Adelaide and Dyson told is true) was encouraged to openly romance Adelaide Bartlett by Edwin's permission. Edwin himself was suffering several unpleasant illnesses (including rotting teeth and possibly tapeworms). Edwin was supposedly something of a faddist, believing in animal magnetism as a key to health, but his reported eccentricities are partly based on what was learnt from Adelaide and Dyson. Adelaide's father was rumoured to be a wealthy and possibly even titled member of Queen Victoria's entourage, which had indeed visited France in 1855, possibly Adolphe Collot de la Tremouille, Comte de Thouars d'Escury.

Edwin and Adelaide were married in 1875. According to Adelaide, it was intended to be a platonic marriage, but in 1881 she had a stillborn baby by Edwin; Edwin had refused her (female) nurse's advice to call a (male) doctor during a difficult labour because he did not want another man "to interfere with her". Early in 1885, they met Dyson as the local Wesleyan minister and he became a frequent visitor. Edwin made Dyson executor of his will, in which he left his entire estate to Adelaide, on condition that she did not remarry (a common stipulation in those days). Later Edwin redrew the will, four months before he died, removing the bar on Adelaide remarrying.

Towards the end of 1885, Adelaide asked Dyson to get some chloroform that had been prescribed by the doctor treating Edwin, Dr. Alfred Leach. Leach would later admit that he prescribed it reluctantly, but at the insistence of his patient. Under the laws of the day, one had to sign a book at the chemist's pharmacy as a record of buying medical poisons, but only for large amounts; Dyson bought four small bottles of chloroform instead of one large bottle, and bought them in several shops, claiming that he needed it to remove grease stains. Only after Edwin's death, did Dyson claim to suddenly realize how suspicious his actions were.
