I AM NEMEIN. I AM EMOTIONALLY DETACHED FROM MY KILLINGS. I AM NOT, THEREFORE, A MURDERER. I AM AN INSTRUMENT OF NEMESIS, A PUNISHER.
This is a theme running through a number of blogs on the Dark Web, written by a serial killer. He is highly intelligent and employs philosophical argument to justify a series of gruesome murders. However, he describes the killings in lurid detail, and with such gloating relish, that he utterly negates his delusion of detachment and reveals himself to be a cold-blooded, narcissistic psychopath.
Sheehan and his team rush headlong down a series of blind alleys in the pursuit of the psychopath, who continues to murder his victims with impunity. He is fiendishly clever, utterly ruthless, and tests Sheehan’s famed intuition to the limit. Indeed, Sheehan only learns the truth during a horrific climax when some members of his team experience a most harrowing ‘laceration of the soul’ that they will never be able to forget. It is unlikely that the reader will either.
This is book 4 in the series, but they do not follow on for each other.
