Brazil baby swap
On 25 March 2009 Brazilian mothers Queila Fagundes and Elaine Oliveira gave birth in the same hospital, however they went home with the wrong babies.
The mothers tell the extraordinary story of how they coped with the trauma of being ordered to swap them back after the mistake was discovered.
Lieutenant Colonel Henry Worsley is related to Frank Worsley, who captained the ship Endurance on Ernest Shackleton's ill-fated 1914 expedition to the Antarctic. Shackleton had made an earlier attempt on the South Pole in 1908, and Henry tells us how he recreated this expedition with the help of other descendants of Shackleton's team.
In Shackleton's Footsteps by Henry Worsley is published by Virgin Books.
