But when the school’s beloved librarian is found shot to death in the stacks, Sophie learns that her friend was more complex than she ever knew. Now, Sophie must take on some rigorous deduction homework before the chances for another murder on campus increase exponentially…

Ada Madison launched her academic thriller series with the SQUARE ROOT OF MURDER and follows it up this month with the second in the Professor Sophie Knowles series, THE PROBABILITY OF MURDER.

The series features a college math teacher, Sophie Knowles, at a small New England campus. Sophie’s crew includes her boyfriend and medevac helicopter pilot, Bruce Granville, and her best friend and bead-shop owner, Ariana Volens, plus a campus full of interesting faculty, students and administrator to enrich and sometimes endanger Sophie’s life.

In THE PROBABILITY OF MURDER, Sophie finds herself in the middle of an investigation after her friend, Henley College librarian Charlotte Crocker, is found dead in the library.
