Three Blind Mice (radio play and short story)

Three Blind Mice is the name of a half-hour radio play written by Agatha Christie and broadcast on the BBC Light Programme at 8.00pm on Friday 30 May 1947.

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, the Dennis O'Neill case, of 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 as Dennis O'Neill.

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 saw the potential of expanding the half-hour radio play into a full theatre play and in 1952, The Mousetrap, the play that has the longest initial run of any play in the world, 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.
