Harper Lee's anticipated second novel Go Set A Watchman went on sale across the world at midnight on Monday 13 July.

Fans queued to get their hands on the hardback edition of the novel, which was discovered by Lee's lawyer lying in a safe-deposit box in 2014.

The novel is set 20 years after the events of To Kill A Mockingbird, but was written five years or so before the publication of Lee's Pulitzer Prize-winning book in 1960.
