A thief may have stolen two of Charles Darwin's notebooks, including one containing his iconic 1837 "Tree of Life" sketch, according to Cambridge University Library in England.

The books were last seen in fall 2000, when they were taken from the uber-secure Special Collections Strong Rooms at Cambridge University Library for a photo shoot. During a routine check in January 2001, however, curators discovered that the small blue box holding the books was missing. While it's possible the box was misplaced, exhaustive searches over the years have yielded no results, so the library is considering the possibility that the box was stolen.
