I’m a big fan of Sjöwall and Wahlöö since a friend of mine lend me “Roseanna” (I’m reading those book series in spanish, following the RBA editions.)
I think it never happened with any book. I took a flight from Barcelona to Amsterdam. I started it in El prat, and while I was in the train between Schiphol and Enschede I finished it. Read it in less than a day!
The 8th book of the Martin Beck series, and as most of the series an amazing book to read.
