Fens Phantom

The Fens Phantom is a Boston-based serial killer heard in the Dear detective tapes and whose skeleton lies in the Fens Street sewer in 2287.

Background
The Fens Phantom was a prolific serial killer in Boston before the Great War. He was presumed to have claimed dozens of Bostonian lives, displaying them in the Fens Street sewer, where he claimed as a 'base of operations' of sorts.

Very little is known about the Fens Phantom's physical features, making it likely he was never caught. What is known is he is male with a deep voice, provided he did not alter his voice in his recordings. He was a sadistic/psychopathic individual, evidenced by how he displays his victims for the detective working on his case to see. He also left holotapes (see: Dear detective tapes) for the detective to listen to as they walk through the sewer, insinuating a love of playing with people's heads.

The last tape found in the sewers reveals that the phantom either captured or killed the detective.

Motives
The Phantom shows heavy frustration with society and societal norms, and how he views people as fake and transparent. He voices this in his second detective holotape:

Appearances
The Fens Phantom appears only in Fallout 4.

Behind the scenes
The Fens Phantom is most likely a reference to the Boston Strangler, a serial killer who murdered 13 women in the Boston area in the early 1960s.
