Ryland Grace is the sole survivor on a desperate, last-chance mission—and if he fails, humanity and the earth itself will perish. Except that right now, he doesn’t know that. He can’t even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he’s been asleep for a very, very long time. And he’s just been awakened to find himself millions of miles from home, with nothing but two corpses for company. His crewmates dead, his memories fuzzily returning, Ryland realizes that an impossible task now confronts him. Hurtling through space on this tiny ship, it’s up to him to puzzle out an impossible scientific mystery—and conquer an extinction-level threat to our species. And with the clock ticking down and the nearest human being light-years away, he’s got to do it all alone. Or does he?

Agatha Christie's debut novel was also the first to feature Hercule Poirot, her famously eccentric Belgian detective. A refugee of the Great War, Poirot has settled in England near Styles Court, the country estate of his wealthy benefactor, the elderly Emily Inglethorp. When Emily is poisoned and the authorities are baffled, Poirot puts his prodigious sleuthing skills to work. Suspects are plentiful, including the victim’s much younger husband, her resentful stepsons, her longtime hired companion, a young family friend working as a nurse, and a London specialist on poisons who just happens to be visiting the nearby village. All of them have secrets they are desperate to keep, but none can outwit Poirot as he navigates the ingenious red herrings and plot twists that contribute to Agatha Christie's well-deserved reputation as the queen of mystery. Librarian's note: the first fifteen novels in the Hercule Poirot series are 1) The Mysterious Affair at Styles, 1920; 2) The Murder on the Links, 1923; 3) The Murder of Roger Ackroyd, 1926; 4) The Big Four, 1927; 5) The Mystery of the Blue Train, 1928; 6) Peril at End House, 1932; 7) Lord Edgware Dies, 1933; 8) Murder on the Orient Express, 1934; 9) Three Act Tragedy, 1935; 10) Death in the Clouds, 1935; 11) The A.B.C. Murders, 1936; 12) Murder in Mesopotamia, 1936; 13) Cards on the Table, 1936; 14) Dumb Witness, 1937; and 15) Death on the Nile, 1937. Poirot also appears, in this period, in a play, Black Coffee, 1930, and two collections of short stories, Poirot Investigates, 1924, and Murder in the Mews, 1937. Each novel and short story has its own entry on Goodreads.
