Not my cup of tea. I am baffled by the 5 star reviews because I agree with the one and two star reviews: there are too many undeveloped characters flitting in and out, the story is fantastic and unbelievable, the "mystery" doesn't make much sense and the conclusion was totally unsatisfactory. How Steve sussed out the big bad guy at the end was never fully explained. I gutted through the whole book thinking that all would be wrapped up with a glorious reveal that tied up all the loose ends but I was sorely disappointed. I love a good mystery that makes sense but this one was not in that category. Stick to your Thursday Murder Club mysteries, Mr. Osman.
