Theatre preview: Daniel Hit By A Train, Eastleigh

Close to St Paul's Cathedral is one of London's most intriguing green spaces. Postman's Park contains the Watts Memorial Of Heroic Deeds, which commemorates acts of selfless heroism by ordinary people who died while trying to save others. The memorial has already featured in Patrick Marber's Closer - one of the characters takes her name from Alice Ayres, who died saving three children from a burning house. Now Lone Twin offers a new piece that tells the stories of the 53 people whose names appear on the plaques.
