Coraline Watson brings her yellow-naped Amazon parrot to the library one night for the Birder's Club meeting, and Liddie takes an instant liking to the beautiful bird. Anne doesn't pay much attention to Coraline's wild stories about spies from a nearby chemical company, until the next morning, when the parrot, Lorenzo, appears at Liddie's window. Anne tries to return the bird, but Coraline's house is dark and empty, the front window is broken, and no one knows where Coraline has gone. Did she stumble across some actual intrigue? Are her theories true about the chemical company trying to steal a local bird refuge for its own use? Or has Coraline managed to abscond with the Birders Club funds? Meanwhile, Liddie is taken with Lorenzo and wants a parrot of her own. There's even a cage in the attic it could live in. When Anne examines the cage, she realizes it was built for carrier pigeons. Did Aunt Edie own them? Anne's research leads to a fascinating discovery in the great anut's past.
