Thomas Dangerfield (c. 165022 June 1685) was an English conspirator, who became one of the principal informers in the Popish Plot. His violent death at the hands of the barrister Robert Francis was clearly a homicide, although whether the killing was murder or manslaughter was a matter of considerable public debate at the time. Biography Dangerfield was born about 1650 at Waltham Abbey, Essex, the son of a farmer. At the age of about 12 in about 1662, he ran away from home to London, and never returned to his home. He began his career of crime by robbing his father of both horses and money, and, after a rambling life, which brought him to Scotland, France, Spain and Portugal, took to coining counterfeit money, for which offence and numerous others he was many times imprisoned: it was said later that to describe his career one need simply list every capital crime known to English law.

Mrs Elizabeth Cellier, in whose house the meal tub was found, was a well-known Roman Catholic midwife and almoner to Elizabeth Herbert, Marchioness of Powis. She had rescued Dangerfield from a debtors' prison and befriended him when he posed as a Catholic. She was, with her patroness Lady Powis, tried for high treason but acquitted in 1680: with the general waning of hysteria, men as disreputable as Dangerfield were no longer considered to be credible witnesses. For a time Dangerfield was used as a secondary witness in the Popish Plot trials to supplement the evidence of Titus Oates and William Bedloe. However, his character was so unsavoury, even compared to that of the other informers, that Chief Justice William Scroggs, who knew his record of crime thoroughly, began instructing juries to disregard the evidence of "so notorious
