Agatha Christie's Typewriter

This typewriter was used by Agatha Christie to write many of her novels. The typewriter has a future-telling like quality, that 24 hours before a crime is done, it will type out the criminals, location, date, damages, etc. Although, the typewriter will never mention a butler.

Origin
Dame Agatha Mary Clarissa Christie, DBE (born Miller; 15 September 1890 – 12 January 1976) was an English crime novelist, short story writer, and playwright. She also wrote six romances under the name Mary Westmacott, but she is best remembered for the 66 detective novels and 14 short story collections she wrote under her own name, most of which revolve around the investigations of such characters as Hercule Poirot, Miss Jane Marple and Tommy and Tuppence. She also wrote the world's longest-running play, The Mousetrap.

Effect
24 hours before a crime, the typewriter will produce a record, including the criminals, date, location, damages, and any other information. It also contains an infinite amount of paper and ink. But, it only works in a 10 mile radius and never mentions butlers.
