From the Amazon page: When Cassie Coburn moved to London, she never thought she'd be involved in a quadruple homicide. After a car accident ended her medical career before it even started, Cassie moved to London on a whim, expecting to see the sights and live the typical tourist backpacker lifestyle. Instead she finds herself accompanying a French private detective, Violet Despuis, as they attempt to find out who poisoned four people in the middle of London. Cassie's life soon includes this crazy detective, an ancient landlady with a curious past, a mischievous orange cat who likes going for walks on a leash, and a super hot pathologist that Cassie is sure is out of her league. And they haven't even found the murderer yet...The Cassie Coburn mysteries are a cozy mystery series featuring a Sherlock-Holmes style sleuth. If you want a light, fun, modern mystery featuring a San Francisco girl totally out of her element in London, and a crazy French woman who happens to be very good at noticing things, then this is the series for you.

As it says, it’s a Sherlock Holmes-style story. It was pretty obvious, though both ’Sherlock’ and ’Watson’ have their genders changed. All I can say is I like the characters, mainly Cassie. Violet is quite a bit like Sherlock - arrogant and a bit abrupt, but fun in a way. The story is well written and as I said, because I like the characters I wanted to find out what would happen. I also enjoyed reading about how Cassie made herself at home in London. As someone who has moved quite a few times in the past year, this made me nod in recognition at some of her experiences. The book is no longer free, except as an audio book, as part of an Audible trial. The paperback isn’t that expensive, and I would probably have bought it if I’d known how good it was.
