The Log Lady (Margaret) was one of the more memorable characters in "Twin Peaks", the television series on which this book is based (see "Objects/Places" - Twin Peaks, The Series"). She was, and is in the book, portrayed as being strange and eccentric, with an almost otherworldly awareness of people, events, and omens. In the "...Diary...", she offers Laura insight into herself and into some of the circumstances of her life, insight which while not always acted upon is, according to Laura's writings, usually recalled.
