The Ardlamont murder (also known as the Ardlamont mystery and the Monson case), which took place in Argyll, Scotland, on 10 August 1893, gave rise to two high-profile court cases: a murder trial in Edinburgh (HM Advocate v Monson), and a defamation trial in London (Monson v Tussauds Ltd) the following year.
Alfred John Monson received the Scottish verdict of "not proven" in his High Court of Justiciary trial for the murder of Cecil Hambrough. Then, in 1894, he sued Madame Tussauds for libel and was awarded one farthing (the lowest possible amount at the time) in damages. The case established the principle of "libel by innuendo" in English law, and Monson v Tussauds Ltd has been used to draw up defamation laws in many countries since.
A notorious case at the time, the trial received renewed attention when it was noted that Joseph Bell, revealed as the inspiration for the popular fictional character Sherlock Holmes, had been called as an expert witness at the murder trial.
Alfred John Monson began working as a gentleman's tutor for the Hambrough family in 1891. On 10 August 1893, Alfred John Monson took Cecil Hambrough, his 20-year-old pupil, for a day's hunting in an area of woodland on the Ardlamont Estate in Argyll. A third man joined them, Edward Scott, a friend of Monson who had arrived at the estate a few days earlier.
Estate workers heard a shot, then saw Monson and Scott running to Ardlamont House carrying the guns. They were cleaning the weapons when the estate butler asked what had become of Mr, Hambrough. Monson replied that he had shot himself in the head by accident while climbing a fence.
Investigation and trial
When the incident was reported, a member of the Inverary procurator fiscal's office was sent to the estate. He returned, saying it had been a tragic accident. However, two weeks later, Monson appeared at the fiscal's office to report that Hambrough had taken out two life insurance policies worth £20,000 only six days before he died, and that they were made out in the name of Monson’s wife. After thorough searches of the estate and interviews with staff, Monson was charged with murder. Scott, now on the run, was named as his accomplice.
Among the witnesses for the prosecution was Joseph Bell, the Edinburgh surgeon and forensic detective. He told the jury that, in his opinion, Monson had murdered Cecil Hambrough. However, sufficient doubt had been sowed in the minds of the jury by Monson's advocate John Comrie Thomson, and Monson was set free with the verdict of "not proven."
Libel by innuendo
In 1894 Madame Tussauds in London erected a waxwork of Monson at the entrance to its Chamber of Horrors, bearing a gun. Monson took exception, sued the company and was awarded one farthing in damages. The case established the principle of "libel by innuendo" and Monson v Tussauds, which has been used to draw up defamation laws in many countries since. To prove libel, there must be publication in permanent form, but this need not be in words.
