     She was known to millions as the "Queen of Crime" or the " Duchess (女公爵) of death". But surprisingly,

she hated violence and blood, and knew nothing of the weapons most often used in murder."I don't think I dare

look at a really horrible and damaged body." Agatha Christie once said.

     But her pen dared travel where her eyes would not. In a 50-year writing career, Christie's murder stories

made her the world's best-known mystery writer. She is outsold only by the Bible and Shakespeare.

     Her works have been turned into films and TV series, and a line of computer games is to be released over

the next six years.

     "My grandmother liked to use new ways to reach people who wanted to enjoy her work," said Christie's

grandson, Mathew Pri- chard."Turning her stories into PC games allows us to introduce classic mysteries to

new audiences.

     Born in 1890 in England, Christie was educated at home and began her writing career while working as a

nurse during World War I. She went on to produce 79 novels and numerous short sto- ries, dying at the age

of 86.

     "With her knowledge of murder, Christie could have been a teacher at police academies," said one fan.
