The stories of the US short-story writer O. Henry, real name William Sydney Porter (1862-1910), are characterised by their irony and by their surprise endings, which became something of a signature of a good O. Henry short story. The 1907 story ‘The Last Leaf’ is among his most famous: along with ‘The Gift of the Magi’ it may be the best-known O. Henry story of all.
