Lemony Snicket's A Series of Unfortunate Events: The Wide Window

Mr. Poe takes the Baudelaires to live with their Aunt Josephine, an irrationally frightened woman who lives in a dilapidated house overlooking Lake Lachrymose. She refuses to answer questions about their parents, so the siblings pursue answers themselves around her house, and discover their parents were members of a secret organization, with spyglasses being used as useful devices. They are also shocked to find out that Josephine was once fierce and formidable, and developed her phobias after the death of her husband. Olaf, who has followed the Baudelaires, disguises himself as a sailor named Captain Sham before pretending to fall in love with Josephine.
