Dennis Lehane, is one of the few writers of thrillers "fashionable" who can combine, beyond the impressive intrigues that have earned him a number of successful film adaptations, a beautiful writing with elegance great depth of the characters, clearly written in a geographic location (Boston) and a socio-economic context (the original Irish proletariat). So that if even if we can find a lot of things to complain - for once - the plot of this "Darkness ..." even when dating 96 (serial killer implausible, little surprise in the final revelation of the culprit, last cliché-like confrontation scene that falls quite flat), the reading pleasure is permanent: they laughed good heart with humorous projections that abound in the patient - and superb - exhibition characters and their environment, sincerely we shiver with them when our heroes turn become victims, in short it vibrates intensely throughout, almost, this very human thriller, and often very touching. Lehane is a master.
