L'énigme de la chambre 622

It's another murder mystery with layers upon layers, which I like. But this time, the setting is Dicker's Switzerland, and himself as a character. As always, a very engaging page-turner.

Overall, a pretty engrossing story. I was particularly submerged in Matthew's story line. It's a shame that more readers have not discovered this and I am continuing with book #2 of series very soon.
