The plot is well put together, really very fascinating history and viewing. He has this way of distilling the suspense in small doses. The chapters are ongoing and at the end leave us "outstanding", prompting us to continue to know what happened.
The atmosphere a little cold, dark but not black, characters with their dark sides, this is all that we are quickly taken by the plot (from the first page). The same is true for the other books I've read by this author.
I recommend this book and this author more generally to all those who love thrillers, detective stories. Author out if you do not know.
