Here's a real life mystery for you which I found on the BBC today.
It's about two people who disappeared many years ago in Iceland. Several people were arrested for their murders. And although they could not remember doing anything, they confessed and as a result spent years in prison. How was this possible?
Read the story and watch the videos, which are almost entirely in English. Then share your reactions with us. What do you think really happened?
On another subject, there is still time for you to listen to Six Minute English on 'Dark Tourism'. See the previous post. Many thanks to Federica, Filomena, Manola and Marcello, who have already done the Quiz. So can you! We look forward to your answers.
More later this week.
