A fine example of Lovecraft's early work. While it lacks in creativity when compared to his more famous work, it is a pleasure to see the seeds of his infamous techniques being played with, and despite the simplicity of this story it is still crammed full of paralysing, indescribable fear and paranoia.
The opening lines submerge us straight into mind of our scared yet unwaveringly genteel mannered protagonist as he describes to us his dire situation. "The horrible conclusion which had been gradually obtruding itself upon my confused and reluctant mind was now an awful certainty. I was lost, completely, hopelessly lost in the vast and labyrinthine recesses of the Mammoth Cave."
The immediacy of the situation is typical of Lovecraft; we know right away that somethings not right dispite there being nothing to go by except the protagonists demeanor. The introduction of a tangible horror element, again in typical Lovecraft fashion, is barely exposed until later on, and even then is never fully revealed to us.
I'm a big fan of hiding things in the dark. Whether it is hidden physically in shadows, or merely incomprehensible. I'll never forget a quote I read online from Howard: "The oldest and strongest emotion of mankind is fear, and the oldest and strongest kind of fear is fear of the unknown."
I'm glad I decided to start reading Howards less known works, for I have discovered within them the exact same ingredients I became addicted to when I first discovered The Call of Cthulhu many years ago.
While technically not a highly rateable story, I would recommend every horror fan reads this.
