Northwest Argentina, March of 1953.

While the sweltering suns shown outside, 18-year-old Florencio Fernandez

slumbered inside a mountain cave.

There in total darkness, he slept, building up his energy for a night on the town.

After sunset, Fernandez awakened and dressed himself in his usual attire,

a black shirt, pants, and a cloak.

He emerged from his hideout and walked into the nearby town of Monteros.

He was on the hunt for the perfect woman.

But instead of searching for her at a nightclub or a bar,

he looked for her at her home.

After peeking inside various windows, he eventually found a seemingly lonely woman.

Fernandez watched her house, observing her eat dinner, and washed the dishes.

All the while, he remained on the lookout, just in case someone arrived to join her.

After a few hours, she started getting ready for bed.

And he realized no one else was coming to join her.

The woman was everything he was looking for, vibrant, healthy, and single.

But Fernandez wasn't looking for love or sex.

He wanted to drink her blood.

Hi, I'm Greg Poulson.
