The Campden Wonder is the name given to events surrounding the return of a man thought murdered in the town of Chipping Campden, Gloucestershire, in the 17th century. A family servant and the servant's mother and brother were hanged for killing their master, but following the man's return it became clear that no murder had taken place, despite the testimony of one of the accused. The story attracted popular attention in England in the years 1660–1662.
On 16 August 1660 a 70-year-old man named William Harrison left his home in Chipping Campden, intending to walk two miles to the village of Charingworth. When he did not return home at the expected time his wife sent his manservant John Perry to look for him. Neither Harrison nor Perry had returned by the next morning.
Edward Harrison, William Harrison's son, was then sent out to look for the pair and on his way to Charingworth he met John Perry. The servant said that he had not been able to find his master, and he and Edward continued to Ebrington, where they questioned one of the tenants whom Harrison had been going to see. The tenant said that Harrison had been there the previous night. Edward Harrison and John Perry then went to the village of Paxford, but their search proved fruitless.
Edward and John then headed back to Chipping Campden. During the journey they heard that some items belonging to William Harrison had been discovered on the main road between Chipping Campden and Ebrington. These included a hat, a shirt and a neckband. Although the hat had been slashed by a sharp implement, and the shirt and the neckband were covered in blood, there was no sign of the body of William Harrison.
Under questioning John Perry said that he knew Harrison had been murdered, but claimed to be innocent of the crime. He then said that his mother, Joan, and his brother, Richard, had killed Harrison for his money and hidden the body. Joan and Richard denied that they had had anything to do with Harrison's disappearance, but John kept up his assertion that they were guilty claiming they had dumped his body in a millpond. The pond was dredged, but no body was found.
The first court hearings dealt with charges linked to a plot to steal money from William Harrison. Despite his mother and brother pleading "not guilty", John Perry's testimony convinced the jury based on the following:
The defendants had all changed their pleas to guilty, because as first time offenders they were granted a free pardon under the Indemnity and Oblivion Act of 1660. Stratmann states that this was a bad piece of advice by the lawyers for the defendants. However, at the time, the judge refused to prosecute the three for murder as there was no body.
