Synopsis: The prize possession of the Sheldon Library is nine leaves of a Gutenberg Bible, worth a small fortune. The leaves are stolen from the library's safe. DA Dan Farrell and reporter Wade (tapped as a special investigator) discuss possible identities of the thief. 

Dr. Prentiss and Alfredo Gonzales have been at odds over the years. Prentiss obtained the Gutenberg leaves, but Gonzales claims they are forgeries. Quentin Ulman has been known to steal various items from the library but has never been prosecuted - and he is having relationships with two different women. Winifred Gonzales chases every man she encounters. 

Almost immediately after the theft, Quentin Ulman is found dead, his body torched on the little-used road in front of the library's off-site bindery building where books are repaired.

The investigation gathers facts, and after a society party, Winifred is found dead in her burned out car.

Wade looks into the deaths, and finds love triangles as well as complications arising from a convoluted will left by the library's founder.
