Dr. Sophie Knowles loves using puzzles to make math fun for students. But when winter seizes Henley College, she must thaw out a cold case to track down a killer—her most difficult puzzle yet . . .
Winter Intersession is in full swing, and campus is buzzing over the concert celebrating the bell tower’s reopening. The building has been shuttered for twenty-five years, and Sophie’s shocked to learn why—a student leapt from it to her death. But she’s even more troubled by the secrecy surrounding the case. After Sophie performs some quick calculations, she’s left with a nagging question: Was it really suicide?
When one of Sophie’s favorite students, a performer in the concert, is brutally beaten and left in a coma, Sophie’s mind kicks into overdrive. The horrific incidents seem too coincidental to be unrelated, but can Sophie put together the pieces from a twenty-five-year-old murder before any other students get hurt?

Henley College has decided to offer a Winter Intersession over the holiday break, 4 weeks of classes, 3 credits each, 31 days braving the cold winter weather on campus. Dr. Sophie Knowles in teaching 2 classes, something she could deal with but then she learns the heating system in Benjamin Franklin Hall is not working and she also has to park way across campus as construction crews continue to work restoring the college’s bell tower and carillon, the huge instrument that consists of huge bells and the keyboard that play beautiful melodies. While she is looking forward to the bell tower reopening she is not happy about the cold windy walk only to enter the cold drafty building. The bell tower has been closed for 25 years and Sophie is shocked to learn why—a student apparently leapt from it to her death but there seems to be so many secrets about the case, Sophie wonders if it really was a suicide. Then one of Sophie’s favorite students, Jenn Marshall, is attacked in broad daylight on campus. The fact that she is one of the students that will be playing the carillon when the tower reopens just like the girl 25 years before seems just a little too coincidental to math professor Sophie. It seems like a perfect puzzle for her to figure out before someone else gets hurt. Dollycas’s Thoughts How come there were no professors like Dr. Sophie Knowles when I was in college? I absolutely hated math and the classes were so boring. Sophie is a great amateur sleuth with her analytical mind. Her emergency helicopter boyfriend, Bruce, is a thrill seeker, who goes on hikes up icy mountains. He prefers Sophie stay out of these investigations but when their friend Detective Virgil Mitchell asks for her help all he can do is try to keep her safe. These three characters are all fantastic and I enjoy their interplay so much. Madison really drew me in to this story with the mystery surrounding the carillon. My children all played in the bell choir of our church and understanding this on this much larger scale was very interesting. I love hearing music from the bell towers but never knew the mechanics behind it. The way the cold case and the new case are written and how they may be connected is masterful. There is a lot of information and misdirection that keeps us readers on our toes. I thought I had this one figured out but I was wrong. This entire series is very entertaining and this 4th installment is the best one yet!! The author also includes some brain teasers and puzzles at the back of the book. Maybe a few brain exercises will give me a better chance at solving the next mystery she tests us with.
Who better to be a great amateur sleuth than a math professor? The Quotient of Murder is the fourth book in the Sophie Knowles Mystery series by Ada Madison. Madison's main character Sophie Knowles is a Math professor at a small New England college and she dabbles a bit in puzzles, brain teasers and murder. Her powers of deduction will challenge readers who enjoy deductive reasoning, probabilities and even a bit of science. But you don't have to be a Math geek to be entertained by this great mystery. A great addition to a very intelligent series! I'll be the first to admit that I am not good at math. I struggled with it during my whole school career, basically because I thought it was boring. Had Sophie Knowles been my professor things might have been different. One of the things that I like so much about this character is that Knowles makes Math fun. She gives her students puzzles and brain teasers that show how the mechanics of Math works but still keeps it interesting. I liked that whole idea along with the puzzles Ada Madison puts in the back of each of her books in this series. Great food for thought! The mystery is this one was quite original. Apparently, Henley college's bell tower has been boarded up for over 20 years. Now that the tower is to be reopened there is a lot of speculation as to why it was closed in the first place. When one of Sophie's students who is supposed to be one of the new bell ringers is beaten and left for dead, Sophie starts to listen a little closer to the gossip about a long ago suicide. I thought Madison crafted a very thoughtful and well plotted mystery here. Sophie is trying to correlate the data on the suicide from the past and figures out that is can't have been a suicide, it was murder and it is related to this latest incident as well. Madison does a fantastic job of keeping readers off balance with this one. There is a lot of information and evidence, but it takes someone with a mind like Sophie's to figure it all out. I love the way her mind works in this series. You can see those gears turning as she uses Math to put two and two together. This series will appeal to readers who love Math, as well as, those of us who are more challenged...LOL. One of the things I like about this series is the relationships that Madison has created for Sophie, not just with her students but with others as well. I like Sophie's relationship with her boyfriend, Bruce. Bruce is a medivac pilot and that adds not only a romantic element to the stories at times, but also creates tension with is vocation. I also like how she interacts with Vigil. Sometimes amateur sleuths have issues with the police and sometimes they get on rather well. I like the way these interact with each other and essentially help each other solve the crime. This is a great series that you have to try if you haven't read anything by this author. It's intelligent and challenging and most of all, it's a series that is a lot of fun trying to figure out. I didn't get this one til the very end. I had no clue and that's rare. I generally have an inkling of who is at fault in most cases, but not this one. It was a total surprise.
