Invisible Helix is part of a detective series by the author Keigo Hishigano, I believe it's popular as the Detective Galileo series and this is the latest title. Our central character Sonoka, is a quite, shy, introverted, unambitious girl who lives with her mother and works at a flower shop while also studying design. 

Her mother passes away quite unexpectedly and suddenly, she discovers this when she returns home one evening and finds her passed out on the bathroom floor. After rushing her to hospital, ske passes away in the next few hours. Being an only child of an orphaned mother, with no father ever in the picture, she is all alone in the world. Her mother's close friend Nae, being her only acquaintance left in the world she knows and was close with at some point. Partly due to loneliness and partly due to naivite she ends up in a relationship with a man who might not be what he seems at first. 

As time goes it's clear to her as she endures abuse and ends up supporting him while he's out of work, that she needs to leave him. Having being alienated from her few friends and acquaintances she sees a ray of hope when she meets a woman claiming to be her grandmother. Though she knows it not to be possible, under pressure from her boyfriend she carries on with the farce to claim financial benefits. 

It all changes and turns sinister when her boyfriend is found dead after her grandmother claims to have taken care of it. She goes on the run with Nae and is off the grid while the police start their investigation and search for her too. 

What I loved - 

The quite, unassuming manner of the police investigation. They go about their investigation in a logical,  on dramatic way it's almost like watching a synchronised swimming session. 

Ofcourse, what I most enjoyed is how I wasn't able to guess who the killer was. The pages flew especially as there was so much suspense surrounding all the key characters we meet. 

A little glimpse into the Japanese nightlife and how the police detectives go about their work was the heart of the story. 

Theh best part was the professor who joined the dots before the police could and how he single handedly solved the case. 

This is one of the cosy whodunnits I enjoyed and you will too as it's a nicely placed quick read you can finish in a couple of reads.
