Hi, I'm looking for any contacts or information about Brian Newell, the author of short story
"What devil wants"/"What does the devil" (which is a part of famous library "World's shortest
stories"). Any idea, citizens? Thank you

Google is your friend.

Its also very possible the Author like most discourages unsolicited direct contact. You can try going through the Publisher or publicist.

I just read all of the world's shortest stories. Didn't see a Brian Newell amongst the lot. Maybe he shortened his name.

Brian Newell - What the Devil Wants
"Two boys stood and watched as Satan slowly goes away. Brilliance of his hypnotic eyes still nebula their heads.
- Look, what he wanted from you?
- My soul. And from you?
- Coins for a pay phone. He urgently needed a call.
- Want to get something to eat?
- I want to, but now I have no money.
- Okay. I have a lot."

Not a bad devil story. Don't know how you found it.

Here's my shortest history of homo sapiens

**************LUCY AND THE BEAN*************
One fine day 3 million years ago, Lucy Austra plucked a bean from a pod on a small tree, and chewed on it. It gave her a lift, so she took several home to her test kitchens, where she tried variations of roasting, grinding, and brewing, and within 3 wired days she was running around on 2 feet and had a string of coffee shops across the savannah. Her fellow hominids were still on all fours, however, resulting in spillage on her clean floors and a lawsuit or two, so she put a 5 bean sign out to give advice on standing upright, thereby creating a supply chain of beans, and inventing the concept of self-esteem, really just a ploy to sell more coffee.

It was in one of the first hits when I searched "Brian Newell devil wants" (without quote marks).

I didn't see any way to contact him. He might be on Facebook.
