Echenoz is unique, exceptional and a delight, every single time.
Readers looking for an Agatha Christie-like thing are looking for the wrong thing; Chandler-lovers the same.
THe genre is not the book, and here Echenoz (as he did in other novels) has fun with the detective genre but this is not a thriller - nor does it matter whether the plot is clear or not, whether you get it or not. Remember the Maltese Falcon? Who cares about the plot?!
His style, his voice, his thoughts, his epigrammes: unique, world-class.
