The trial, which lasted twelve hours, took place on February 29, 1752, in the Divinity School of the University. The prisoner was “sedate and composed without levity or dejection.” Accused of felony, she had properly counsel only for points of law, but at her request they were allowed to examine and cross-examine the witnesses. Herself spoke a defence possibly prepared by her advisers, for though the style be artless, the reasoning is exceeding ingenious. She admitted she was passionate and thus accounted for some hasty expressions; the malevolence of servants had exaggerated these. Betty Binfield, one of the maids, was credibly reported to have said of her, “she should be glad to see the black bitch go up the ladder to be hanged.” But the powder? Impossible to deny she had administered that. “I gave it to procure his love.” Cranstoun, she affirmed, had sent it from Scotland, assuring her that it would so work, and Scotland, one notes, seemed to everybody “the shores of old romance,” the home of magic incantations and mysterious charms. It was powerfully objected that Francis Blandy had never failed in love to his daughter, but she replied that the drug was given to reconcile her father to Cranstoun. She granted he meant to kill the old man in hopes to get his money, and she was the agent, but (she asserted) the innocent agent, of his wicked purpose. This theory though the best available was beset with difficulties. She had made many incriminating statements, there was the long time over which the doses had been spread, there was her knowledge of its effects on Anne Emmett the charwoman, there was the destruction of Cranstoun’s letters, the production of which would have conclusively shown the exact measure in which guilty knowledge was shared. Finally, there was the attempt to destroy the powder. Bathurst, leading counsel for the Crown, delivered two highly rhetorical speeches, “drawing floods of tears from the most learned audience that perhaps ever attended an English Provincial Tribunal.” The jury after some five minutes’ consultation in the box returned a verdict of “guilty,” which the prisoner received with perfect composure. All she asked was a little time “till I can settle my affairs and make my peace with God,” and this was readily granted. She was left in prison five weeks.
