Having read a lot of Agatha Christie books, I feel like when I do read them I am quite at home. I enjoy her style and she often reuses phrases and idioms throughout her books. 
The Mysterious Affair at Styles was her first Hercule Poirot book, and who doesn't like Poirot? I can't say this was the best book by her that I've ever read, but it is fun to see the detective in his debut. I like that this book had some courtroom scenes, I love courtroom dramas. As this is an earlier book for Christie, I felt that the suspects were a little less fleshed out than I remember suspects being in future books. This made it a little harder to keep up with everybody, but as usual there was a good twist ending.
If you are a Christie fan and want a fast read, pick this up for sure.

I had originally attempted to read this book as a teenager and having found it rather difficult to get into gave up (my tbr at the time was far too long a list to dawdle). I'm very glad I decided to revisit it, as I am now begining to read through authors works in full turning my attention to Agatha Christie's remarkable number of books felt like the next logical step, but I hesitated to attempt to read this first installment myself again recalling how difficult it had been. 
I was delighted to find the audiobook narrated by Hugh Fraser as I remember seeing him as Hastings when my grandparents and I would watch Poirot in the evenings, and I must say that delight continued as I listened! He posses a wonderful ability to vary his voice for different roles and keep them consistent to the character each time with minimal wavering and he's capable of imparting the right emotion for the lines as necessary. I truly felt he was baffled when Hastings was and infuriated when Poirot was - it was far easier to listen to than to read I found, purely because the narration kept it so interestingly vivid. 

The book itself is fun and all together not too long, enough intrigue to keep my attention with a satisfying ending that did not feel far fetched (as some "twists" end up). The characters feel alive and of the time, the setting is easily visualised and context is given through the narration plainly and understandably. The language used may be difficult to read if one isn't used to the way people talked at the time but is easy enough to become comfortable with - especially when listening to it.

Overall a wonderful book and a lovely time. 4.75/5 ⭐

This audio adaptation is excellent, with an absolute perfect performance by Peter Dinkledge as Poirot. The only drawback to the audio adaptation is the dinner scenes, where the chewing noises were a bit too much. If you suffer from misophonoia, you may want to skip forward during that scene.
