Drowned Wednesday is the third book in The Keys to the Kingdom series by Garth Nix. It continues the story of Arthur Pehaligon and his quest to fulfil a mysterious Will in order to reclaim an otherworldly House from seven antagonistic Trustees. Following the events of the previous novel, Arthur must secure the third part of the Will from a fiendish pirate in order to save the Border Sea from Drowned Wednesday's insatiable appetite. Plot Picking up after the events of Grim Tuesday, Arthur discusses Drowned Wednesday's invitation to meet for lunch with Leaf while he is hospitalized. The two are skeptical as to whether Wednesday can be trusted, but then the hospital room is suddenly filled with water and the two find themselves transported to the Border Sea, Wednesday's domain. Leaf and Arthur are separated when Leaf is picked up by the Flying Mantis, a large ship, and Arthur is left behind. Arthur uses the Mariner's medallion to summon help but his call goes unanswered.
