Dorothy and Agatha

Dorothy and Agatha is a novel written by Gaylord Larsen.

Plot summary
When the corpse of an unidentified man is found in Dorothy L. Sayers's English village home, where she is preparing for the 1937 production of her religious play, The Zeal in Thy House, Agatha Christie agrees to investigate. Christie discovers a secret Sayers had been trying desperately to hide, and despite some mutual antipathy, the novelists join forces. With their only clue the unusual nature of the gun used in the killing, the duo, pursued by a crass and persistent female American journalist, uncovers a tie to a gassing incident during WW I which had also involved Sayers's husband, the now alcoholic MacDonald Fleming. Another death and two near-fatalities occur before the killer is unmasked and Sayers extricated from her difficulties.
