I just finished reading Three Seconds by Swedish writers Roslund and Hellstrom. It was pretty slow the first 150-200 pages. I really didn't understand why Piet (the main character) was doing what he was doing and at times I was ticked off at him. I even considered changing books because it just wasn't getting going! But once Piet was put in prison (which you read on the book flap) it gets AWESOME!! I read the last 300 pages in two days. I finally had to just sit and read it until I was finished.
This is the fifth book in a series, but there is no need to have read the first 4 to understand what was going on in the story. There is a detective, Ewert Grens, that has a back story, but it doesn't drive the book by any means, and you do find out basically what had happened. Also, of the four previous books, only one other book had been translated.
I would definitely recommend this book, but be prepared to sit non-stop for the last 300 pages!!!
