The lawyer-dominated adversary system of criminal trial, which now typifies practice in Anglo-American legal systems, was developed in England in the 18th century. This text shows how and why lawyers were able to capture the trial.

‘For the sake of decency, gentlemen, don't hang me high.’ This was the last request of modest murderess Mary Blandy, who was hanged for poisoning her father in 1752. Concerned that the young men in the crowd who had thronged to see her execution might look up her skirts as she was ‘turned off’ by the hangman, this last nod to propriety might appear farcical in one who was about to meet her maker. Yet this was just another aspect of a case which attracted so much public attention in its day that some determined spectators even went to the lengths of climbing through the courtroom windows to get a glimpse of Mary while on trial. Indeed her case remained newsworthy for the best part of 1752, for months garnering endless scrutiny and mixed reaction in the popular press. Opinions are certainly still divided on the matter of Mary’s ‘intention’ in the poisoning of her father, and the extent to which her coercive lover, Captain William Cranstoun, was responsible for this murder by proxy. Yet Mary Blandy’s trial was also notable in that it was the first time that detailed medical evidence had been presented in a court of law on a charge of murder by poisoning, and the first time that any court had accepted toxicological evidence in an arsenic poisoning case. The forensic legacy of the acceptance of Dr Anthony Addington’s application of chemistry to a criminal investigation is another compelling aspect of The First Forensic Hanging.

In the first half of the 18th century there was an explosion in the volume and variety of crime literature published in London. This was a 'golden age of writing about crime', when the older genres of criminal biographies, social policy pamphlets and 'last-dying speeches' were joined by a raft of new publications, including newspapers, periodicals, graphic prints, the Old Bailey Proceedings and the Ordinary's Account of malefactors executed at Tyburn. By the early 18th century propertied Londoners read a wider array of printed texts and images about criminal offenders – highwaymen, housebreakers, murderers, pickpockets and the like – than ever before or since. Print Culture, Crime and Justice in 18th-Century London provides the first detailed study of crime reporting across this range of publications to explore the influence of print upon contemporary perceptions of crime and upon the making of the law and its administration in the metropolis. This historical perspective helps us to rethink the relationship between media, the public sphere and criminal justice policy in the present.
