Chamber of Secrets contains some pretty obvious examples of deceit. Lucius Malfoy tricks Ginny into taking Tom Riddle's diary. Harry tricks Lucius Malfoy into freeing his house-elf, Dobby, in turn. Riddle tricks both Ginny and Harry into thinking that he's an honest, upright student – the biggest lie of all. There are also more subtle examples of withholding information, though, much of which stems from feeling of fear and insecurity. For example, Ginny decides not to tell anyone about her suspicions of Riddle's diary until near the end of the book. Also, when Professor Dumbledore asks Harry point-blank if Harry has anything he needs to tell Professor Dumbledore, Harry says no, even though he's been hearing a murderous voice in the walls. In fact, the whole plot of Chamber of Secrets depends on different degrees of manipulation, lies by omission, and outright fibs. Without all of this misinformation, Book 2 wouldn't have the atmosphere of mutual fear and suspicion that distinguishes it from the lighter-hearted Book 1.
