for fear of an attempt of suicide. There was no staff at the Tower [of London] to guard suicidal cases." Trial and execution Casement's trial at bar opened at the Royal Courts of Justice on 26 June 1916 before the Lord Chief Justice (Viscount Reading), Mr Justice Avory, and Mr Justice Horridge. The prosecution had trouble arguing its case. Casement's crimes had been carried out in Germany and the Treason Act 1351 seemed to apply only to activities carried out on English (or arguably British) soil. A close reading of the Act allowed for a broader interpretation: the court decided that a comma should be read in the unpunctuated original Norman-French text, crucially altering the sense so that "in the realm or elsewhere" referred to where acts were done and not just to where the "King's enemies" might be. Afterwards, Casement himself wrote that he was to be "hanged on a comma", leading to the well-used epigram. During his trial, the prosecution (F. E. Smith), who had admired some of Casement's work before he went over to the Germans, informally suggested to the defence barrister (A. M. Sullivan) that they should jointly produce what are now called the "Black Diaries" in evidence, as this would most likely cause the court to find Casement "guilty but insane" and save his life. Casement refused to agree to this and was subsequently found guilty and sentenced to be hanged. Before and during the trial and appeal, the British government secretly circulated some excerpts from Casement's journals, exposing Casement as a "sexual deviant". These included numerous explicit accounts of sexual activity. This aroused public opinion against him and influenced those notables who might otherwise have tried to intervene. Given societal norms and the illegality of homosexuality at the time, support for Casement's reprieve declined in some quarters. The journals became known in the 1950s as the Black Diaries and are still in the National Archives, whilst most of the other exhibits from the trial are in the Crime Museum in London. Casement unsuccessfully appealed against his conviction and death sentence. Those who pleaded for clemency for Casement included Sir Arthur Conan Doyle, who was acquainted with Casement through the work of the Congo Reform Association, poet W. B. Yeats, and playwright George Bernard Shaw. Joseph Conrad could not forgive Casement, nor could Casement's longtime friend, the sculptor Herbert Ward, whose son Charles had been
