The Vernacularly Fastened Door

The Vernacularly Fastening Door is a lock that can only be opened by typing in three unique phrases, "The first phrase is a description of a medical condition that all three Baudelaire children share...The second phrase is the weapon that left you an orphan, Olaf...And the third is the famous unfathomable question in the best-known novel by Richard Wright" (p. 225). In the end, Klaus Baudelaire works alongside Count Olaf to open the door.
