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 ...more

What an entertaining read. I like this series for several reasons. Math isn't one of them--after all, as the t-shirt says, "I was an English major, you do the math." I do, however, send the math puzzles at the back on to my niece who does "do the math."
No, I like the series because the protagonist is female, young, and smart. Sophie is enjoyable. She is attractive, intelligent, funny, a professor, and shows that it is o.k. to be all of those. She has found her place and is accepted for who/what

The Quotient of Murder is the 4th book in the A Professor Sophie Knowles Mystery series.

Sophie Knowles is a professor in Math at Henley College and as a sideline makes math puzzles and brain teasers.

The talk in the teachers lounge is about the rededication of the college's bell tower. It has been closed for some 20 years after the apparent suicide. One of Sophie's promising math students and one who is hopeful to become a bell ringer for the towers reopening. But on her way home from class one d

Since I don't normally write reviews unless I have something specific to say, here's the break down of how I rate my books...

1 star... This book was bad, so bad I may have given up and skipped to the end. I will avoid this author like the plague in the future.

2 stars... This book was not very good, and I won't be reading any more from the author.

3 stars... This book was ok, but I won't go out of my way to read more, But if I find another book by the author for under a dollar I'd pick it up.

Another great addition to a wonderful series. Using my own rating system, I give this book 5 stars = I loved it. Being from a small town in MA, I enjoy the descriptions of the locations. The main characters Sophie, Bruce, and Virgil are awesome, and I enjoyed the new romance that was brought up. I really enjoy cozy mysteries that have a small element of romance in addition to the main crime/plot of the story. Ada Madison is a great author and I highly recommend this series to those who enjoy coz ...more

This series is ok. The writing is pretty good, the stories are a little easy to figure out. This one felt a little forced with Sophie finding out about an old mystery the very day a new mystery happens, and then they happen to be connected. Sophie is on the verge of being just a little too perfect, but it's a series worth reading if you like serial mysteries.

I have a sneaking suspicion that these are not great books. But, they scratch my cozy mystery itch so well! With some math and puzzling to go along side. Not genius, but a great indulgent read for me, anyway.

An alright tale...decidedly "meh" by the end. I doubt I'll seek out the rest of the series...but I did learn a lot about carillons.
Dec 18, 2013 Becky rated it it was amazing
This series gets better with each book, so The Quotient for Murder is the best-to-date! Now I am going to google carillon music, to hear the sounds and look at the instrument!
i enjoyed reading this book, it has it all, a female math professor with carillon bells. A 25 old suicide connected to a current day attack on one of her students.
