~ First Chapter First Paragraph Tuesday Intros ~

First Chapter First Paragraph Tuesday Intros is a weekly meme hosted by Diane at Bibliophile by the Sea every Tuesday. The idea is to share the opening paragraph (maybe two) of a book you've decided to read based on the opening paragraph.  My book choice today is a psychological thriller that's been getting great reviews and I'm so excited to read it.  It's also another perfect title for the R.I.P. Challenge.
Be sure to drop by Bibliophile By the Sea and read Diane's terrific selection this week and be sure to visit and read the contributions of other participants in this terrific meme who can be found in the comments!

Before I Go To Sleep by S. J. Watson

The bedroom is strange. Unfamiliar. I don’t know where I am, how I came to be here. I don’t know how I’m going to get home.
I have spent the night here. I was woken by a woman’s voice – at first I thought she was in bed with me, but then realized she was reading the news and I was hearing a radio alarm – and when I opened my eyes I found myself here. In this room I don’t recognize.
My eyes adjust and I look around in the near dark. A dressing gown hangs off the back of the wardrobe door – suitable for a woman, but someone much older than I am – and some dark-coloured trousers are folded neatly over the back of a chair at the dressing table, but I can make out little else. The alarm clock looks complicated, but I find a button and manage to silence it.
It is then that I hear a juddering intake of breath behind me and realize I am not alone.

What are your thoughts about this opening paragraph? Would you read this book based on these paragraphs?
