Light cozy mystery

The Square Root of Murder is an enjoyable and entertaining cozy mystery with engaging characters and a well developed plot. The characters interact well with each and behave realistically. I look forward to the next book in this series.

Creative new angle for a mystery

I really enjoyed this book, especially because I have read many cozy mysteries with English teachers or librarians or book store owners, but this is the first I've encountered that featured a math professor! It was interesting and fun. I look forward to future books coming out soon!

Math, Mystery and Great Characters!

The Square Root of Murder is the debut book in the Sophie Knowles cozy mystery series. It is an enjoyable book with likable characters and an interesting mystery that kept me guessing. Sophie teaches Math at a small college in MA. An unpopular professor ends up dead and Sophie needs to clear her friend from the suspect list. It is an enjoyable cozy mystery but I found the descriptions were often too much (too many details and too long). Overall, it was good and I will read the next book. The audiobook is narrated by Chris Kenworthy who did a great job and made the characters unique and the audiobook was easy to follow. I received a copy of the audiobook from Camille Minichino for an honest review.

Outstanding murder!

The Square Root of Murder is Book 1 of Professor Sophie Knowles Mystery by Camille Minichino. This mystery was very good. I thought the characters were well written and realistic. I was not sad when the Chemistry Professor was poisoned...my bad, he was a jerk! One thing I really enjoyed was the depth of the clues, I really had to think. Chris Kenworthy gave a wonderful performance as narrator. This is a really good series.

A good cozy mystery.

Sophie's tenacity held my attention throughout.

Chris Kenworthy's narration brought the characters to life.

Nice and cozy little mystery.

As a fan of fast paced thrillers and mysteries, this was a nice 'break" from them while still using my noggin to figure it out before the narrator got to it. The narrator's voice fits very well with the pace of this book. An excellent book for young adults that love mysteries, or someone looking to dip their toes in this genre. Sophie really should change careers and become an investigator!

Murder puzzles

This was a fun cozy mystery! Sophie is a math professor. One of the unpopular professors is found dead. And Sophie really gets herself tangled up in the investigation. The characters were interesting, especially Sophie. The story has a fun theme of mathematics and puzzles. I listened to the audiobook and the narration was really good.

A thoroughly enjoyable listen

I enjoyed this, when I listen I try to imagine the scenes in my head like a film, and the story, the people, the details involved made it such a good listen.

I thoroughly enjoyed the narration it was so pleasant to listen too, my only minor fault was they could have used proper sounds as opposed to talking sounds!

My only other issue was the length (to be fair it put me off starting it earlier), but with the details involved and the story I found it enjoyable and like a book doing a few chapters at a time and then going back over it to remember I now look forward to hopefully listening to the next book.

Returning this one - not for me

I cannot get used to the narrators voice. Eventually grated so much I did not really want to finish book. Story itself very lightweight and not enough content. Only upside was the puzzle bit. Not one I will read again so going to return it.

The Square Root of Murder

This cozy mystery had plenty of suspects and a twist which kept me listening to the audiobook. It's not the best cozy mystery I have read but still not bad.

It all adds up to a good mystery

This was a good mystery and a fun look into university life. The characters were interesting and I thought the puzzle addiction that ran through out the story was an unusual twist. There was a number of suspects, with several motives to keep you guessing. I also liked the fact that the boyfriend is a helicopter pilot and not a detective, there is the required detective in the form of a best friend.
Sophie is a maths professor and a puzzle designer so after a celebration party ends with the death of a hated professor she can't stand back and let the police do there thing. Even if the detective investigating the murder is her boyfriends best friend especially as what little he shares with Sophie points the finger at her teaching assistant and friend Rachel. On summer schedule she has plenty of time to ask questions, which gives her a real puzzle to get to grips with as a number of different pictures is painted about the man she thought she knew. The murder it's self is a puzzle with a number of differing witness statements. Who found the body first? And what is with the disappearing and reappearing cake? As Sophie puzzles it out she also loses some valuable evidence, evidence that she shouldn't have and then she gets called into the dean's office. Can Sophie get to the bottom of the problem before her friend gets arrested?
The narrator was okay but didn't really have much range or difference in her speaking and character voices.

Quite a good mystery set in a college.

I enjoyed this mystery, set in a college, as I like academic sleuths. However I did not enjoy the narrators voice. Her pitch was often too high, the voices she gave the characters were improbable, and the alarm and phone sound effects were awful.
If I want more in the series, I’ll try ebooks, unless there is a different narrator.

Boring!

It beats me how many woeful readers there are. They can totally ruin a decent book. I have given the story 3 stars in the hope that with a different reader it may have been less boring. Between the storyline and the reader, I could not listen any further. If there were any exciting revelations discovered by the use of math methods, I didn’t get to them. I shall be asking for an exchange!
