Agatha Christie was an author of crime novels and the best-selling novelist of all time. Her novels have sold around four billion copies, and she is the author who has been translated into the most languages.
She wrote 66 detective novels and 15 books of short stories before her death in 1976. Now there is going to be a new story about her most famous character, Belgian detective Hercule Poirot.
The new book will be written by crime author Sophie Hannah, and will be set in the late 1920s. She said it was a "huge, huge honour" to be chosen to write the book. It will be published in a year.
One of London's newest buildings has been nicknamed the Walkie Talkie because of its shape. This week it got a new name, the Walkie Scorchie.
This is because sunrays reflected from the building's glass walls apparently melted parts of a car parked nearby. The glass is curved and at this time of year it appears to concentrate the sunlight to a small part of a nearby street.
Shop owners have complained that the light and heat are damaging their businesses, and journalists have proved that it is possible to fry an egg in the sunrays.
The company building the Walkie Talkie have now agreed to pay for the car to be repaired, and have built a screen to protect shops. They say they are looking at longer-term solutions to the problem.
Lipstick has been a cheap treat for women for many years, but the latest sales figures show that nail varnish is catching up fast. In 2011 nail varnish sales were worth GBP221, compared with GBP224 for lipstick. Sales analysts say nail varnish sales will reach GBP233m by the end of the year.
The trend took off last summer during the Olympics when Team GB athletes wore patriotic painted nails, inspiring others to do their own. Sales rose to about a million bottles of varnish a week, and there are nail bars on many shopping streets.
There are now lots of new colours and textures on sale, including varnish which turns nails into tiny blackboards.
The police have said it was "a miracle" that nobody was killed in a road accident involving 130 cars, vans and lorries.
The crashes happened in thick fog on a bridge in the South of England one morning this week. Eight people were badly injured and 35 were taken to hospital. One local politician said he had been asking for speed restrictions on the bridge and lighting since it opened seven years ago.
The crossing is three-quarters of a mile (1.25km) long and rises to 115ft (35m) at its highest point.
