There's a room and none of the occupants know how they got there or why. A nightmare room - a place you don't want to find yourself - ever! Although I did work out very early on what this was about I still enjoyed it very much - so different from the usual thriller. I liked Morgan and Slade, the two main characters, and felt sympathy for their dilemma. This was a great page turner but maybe not for people who only like "cosy" mysteries!
