So good. I really enjoyed this, but wish it had been a but longer. And I Hought that parts of Cassie's backstory we're  a bit confusing. This is why I gave it five stars, but did not favorite it. 

The first book in the Cassie Coburn mystery series (there are four books in this series) follows Cassie after a life changing accident changes her prospects of being a surgeon. Cassie movies from San Francisco to London to get over her depression that still lingers since her accident.  After a bike of her gets stolen she has a hilarious meet up with a French woman named Violet Despuis who is a private detective helping out the London police. Violet takes an interest in Cassie after using her deduction skills on Cassie. Cassie finds herself intrigued by Violet since she has nothing else to do. The duo team up when Violet investigates a supposed serial killer case.

I really liked Cassie a lot. The similarities to Dr. Watson were great, but Silver did her own spin on it. I stead of going to war and suffering from a gambling problem, we have Cassie suffering from depression and an addiction to fast food. And Silver doesn't treat her like a bumbling partner to Violet. Cassie gets increasingly better at deductions with Violet a very good teacher. 

Violet was interesting, but we don't learn much about her except she's estranged from her family. 

I was confused about Cassie's backstory too. She mentions her father, but her mom was a single mother. I thought initially her father died, but another sentence I read made it seem like he abandoned the family. Also Cassie comes into a huge amount of money due to her accident. So her being a cheap skate about lodging (she initially stayed at a hostel) didn't feel real. 

The writing was good and I thought the flow was great. The book moved quickly. I wasn't that interested in Cassie's love interest either. That part ruined the book a bit since it turned it into a more mainstream romance book. 

The final clues that lead to the guilty party was great.
