The story centers around Roberta Langwell, a young female pilot, who embarks on an intriguing series of flights, accompanying a mysterious passenger named Mrs. Pollzoff. As Roberta navigates the skies, she becomes increasingly suspicious of her passenger's true motives, especially after a series of unsettling events raise questions about Mrs. Pollzoff's background and intentions. At the start of the narrative, we are introduced to Roberta and her family as she prepares for her morning flights, interacting with her brother and parents in a warm domestic setting. However, tension builds as Roberta's newfound passenger, Mrs. Pollzoff, displays eccentric behavior during their flights, particularly with her obsession with the ocean and her underhanded request to stay outside lawful boundaries. The opening chapters set the stage for an escalating mystery, hinting at danger when a recent attempted theft at Roberta's family hangar may be connected to her mysterious passenger. As Roberta continues to fly with Mrs. Pollzoff, she finds herself entangled in a web of intrigue that could ultimately threaten her safety. (This is an automatically generated summary.)
