Jane Eyre went on to become one of the most enduring works of English literature.

British Conservative MPs vote at the Carlton Club to withdraw from the coalition government led by David Lloyd George.

The meeting, prompted by backbench unease over Lloyd George's leadership and foreign policy missteps, saw Conservative members decide to fight the next election as an independent party rather than continue the wartime coalition.

The four had been wrongly convicted based on confessions later shown to have been obtained through police coercion, with evidence of fabricated records emerging over the following years. Their release exposed serious flaws in the British justice system's handling of Troubles-era terrorism cases and became one of the country's most notorious miscarriages of justice, prompting wider reforms to police interrogation practices.
