Robin Master's mentor, Elizabeth Barrett, arrives at the estate with her macaw Merlin to research a book on ornithology. The former teacher hits it off famously with Thomas, but becomes so much of a thorn in Higgins's side that he bribes Thomas to help in bringing her visit to an expeditious end by finding Dr. Albert Tessa, the reclusive bird expert she's come to the island to interview. Thomas soon discovers that Elizabeth isn't Robin's mentor, but a K.G.B. agent on a mission to assassinate Tessa, a refugee freedom fighter from the 1956 Hungarian revolt. Meanwhile, Thomas has troubles collecting his fee from a man whose beautiful employee is tough enough to shoot out the Porsche's windscreen to keep Thomas at a distance from her boss.
