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

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.

4 sta

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.

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!
