It was part of an evening of programmes in honour of the eightieth birthday of Queen Mary. The BBC had approached the Queen some months before and asked what programmes she would like to hear. Amongst a selection of music and variety, she requested something by Christie who was a writer she admired. Christie agreed, asking that her fee of one hundred Guineas be donated to the Southport Infirmary Children's Toy Fund.
The idea for the play came from a real-life crime tragedy in 1945 with the death of a boy in foster care. Christie's official biography states that the name of the boy was Daniel O'Neill but contemporary newspaper reports state the name of the boy was Dennis O'Neill, aged twelve. Together with his younger brother, Terence (aged nine) he had been placed in the care of a farmer (Reginald Gough, aged thirty-one) and his wife (Esther, aged twenty-nine) of Bank Farm, Hope Valley, Minsterley, Shropshire, on July 5, 1944. Just over six months later, on January 9, Mrs. Gough rang a local doctor and reported that the boy was having fits. The doctor attended but Dennis died. He was severely malnourished and was covered in three-day old bruises. An inquest was held on February 5, 1945 at which the jury returned a verdict of Dennis having died due to "acute cardiac failure, following violence applied to the front of the chest and back while in a state of under-nourishment due to neglect". Two days before, On Saturday, February 3, Gough had been charged with manslaughter and his wife with having "wilfully ill-treated, neglected and exposed the boy in a manner likely to cause suffering and injury". They went on trial on March 15 and on March 19 both were found guilty of their respective charges. Gough was sentenced to six years and his wife to six months. The Goughs were divorced on October 22, 1946 on the grounds of his cruelty to her but their subsequent fate is not recorded. A first-hand account of Terence O'Neill's story was published by Harper Collins in March 2010 under the title Someone to Love Us (ISBN 9780007350186). A government enquiry by Sir Walter Monckton ensued as a result of the case which on December 13, 1946 resulted in a revised set of rules relating to the placement of children in foster care. These came into effect on January 1, 1947.
- Main article: Three Blind Mice At some point soon after transmission of the radio play the suggestion was made to Christie that she turn it into a short story. This was published in the US in Cosmopolitan magazine in May 1948 and then in the 1950 collection Three Blind Mice and Other Stories. Christie asked that the short story not be published in the UK as long as The Mousetrap continued to run on the stage.
- Main article: The Mousetrap Christie saw the potential of expanding the half-hour radio play into a full theatre play and in 1952, The Mousetrap, first came to the stage. As another play had run on the stage just prior to the Second World War also with the title Three Blind Mice, Christie had to change the name. It was her son-in-law, Anthony Hicks, who suggested The Mousetrap, which is taken from Act III, Scene II of Shakespeare's Hamlet. Allan McClelland, in the role of Christopher Wren, was the only actor to make the transition from the radio production to the stage play. It holds the longest initial run of any play in the world though it was interrupted by the 2020 Covid-19 Crisis.
