The Queen of Mystery has come to Harper Collins! Agatha Christie, the acknowledged mistress of suspense - creator of indomitable sleuth Miss Marple, meticulous Belgian detective Hercule Poirot, and so many other unforgettable characters - brings her entire oeuvre of ingenious whodunits, locked room mysteries, and perplexing puzzles to William Morrow Paperbacks. The Man in the Brown Suit is Christie at her best, as a young woman makes a dangerous decision to investigate a shocking "accidental" death she witnesses at a London tube station.
