DOTTwo teenagers discover the body of a young female lying over a sheet of snow in a residential area near the Shawmut train station. The young woman is the first victim of a string of distinctive murders that leaves almost no clues to the police.

Dorchester is densely populated, but even so, the killer remains unnoticed. The investigators purposefully select a different approach to conduct the investigation, but their methodology fails, the body count continues rising, and the analysis becomes more complex.

Although the sinister perpetrator leaves his deliberate personal stamp on the bodies, he leaves no clues. His gruesomely unique signature puzzles the authorities, and they become very concerned with the unfamiliar patterns.

The killer's evilness is too ruthless, with many wicked things listed against him, but quite apart from his crimes, he hides a secret, almost as heinous. Who is he, so discreet as to be invisible but a real threat spreading terror across the vast region? What message does he leave behind? What motive does he have for committing such acts like these? The unexpectedly terrifying answers will send a chill down your spine and surely will be something you will ponder over for a long time.
