Lépésnyi disappeared

Lépésnyi was last seen on Wednesday after 8 am.

According to the locals, the archaeologist arrived to in the village three weeks ago. He worked on the mysterious excavations with a woman named Farkas (Wolf), and they were very secretive. Lepesnyi stayed at the local inn. No one remembers anything further.
He was last seen by two students from the local elementary school: Zénó K and Mario L. According to these witnesses, on their way to school, they spotted the middle-aged archaeologist in front of the tent, which covered the excavation site. He was muttering gibberish and smiling, while holding up his hands. Mario L. watched him as he slowly disappeared starting from his legs. He left his bag behind on the ground. His records and some letters addressed to a certain S.T. were found in the bag.
The case is being investigated by the police involving experts.

Dear S. T.,

I hope you are doing well, and my letter reaches you.
I have arrived on the site. I am staying at the local inn. It’s actually an ok place. The food is all right as well. Farkas arrives tomorrow. She missed the train. Until she gets here, I’ll check the site out. I am already very excited.
This is IT, I can feel it!
I will write every day.

Truly yours,
Lépésnyi

Dear S. T.,

Farkas arrived. She started the mapping. She is drawing – she never really liked technology. I surveyed the site. Astonishingly exciting. I have never seen anything like this. Full of remains. Most of them are completely intact. A whole community was living here. The foundations of the house are intact as well. It is going to be a lot of work. It’s all so peaceful here.
I miss you, hope to see you soon.

Truly yours: Lépésnyi

Dear S.T.,

Farkas disappeared. You know how she is... She insisted on sleeping out in the field. She has brought along a tent. Up until yesterday, everything went well, but this morning, she was gone. Disappeared without a trace. I hope she is all right. She has always been a strange person, but she was trustworthy. She has never done anything like this before. I am puzzled. I have her drawings. I’ll continue the work alone.

Truly yours: Lépésnyi

Dear S.T.!

The model is ready. It is basically useless. This engineer is going on my
nerves. The film is flashing. He did not take my guidance into account.
Still, it’s nice to see the house as a whole. I wonder how many were living
in there? The remains stem from multiple generations. We are almost
done cataloguing. I don’t want to leave this place. I miss you.

Truly yours: Lépésnyi

Dear S.T.,

I am really suffering. Farkas is still nowhere to be found. I have the feeling that she is in the House. I cannot explain this. Please don’t think that I am insane. The whole thing seems to be coming to life. I am sleeping out in the field. They bring the food here as well. It’s only here, where I feel good. I got hold of a tent. I am living here with them. I see them. I was even smelling scents yesterday. Something fresh and very homey. Odours from long-ago. I would like to introduce you to Them.

Truly yours: Lépésnyi
