In the following days, while at work with the other firemen ransacking the book-filled house of an old woman and drenching it in kerosene before the inevitable burning, Montag steals a book before any of his coworkers notice. The woman refuses to leave her house and her books, choosing instead to light a match and burn herself alive. Jarred by the woman's suicide, Montag returns home and hides the stolen book under his pillow. Later, Montag wakes Mildred from her sleep and asks her if she has seen or heard anything about Clarisse McClellan. She reveals that Clarisse's family moved away after Clarisse was hit by a speeding car and died four days ago. Dismayed by her failure to mention this earlier, Montag uneasily tries to fall asleep. Outside he suspects the presence of "The Mechanical Hound", an eight-legged robotic dog-like creature that resides in the firehouse and aids the firemen in hunting book hoarders.
