SciFi and Fantasy Book Club discussion

This SF book was written by a writer known more for mysteries. Came out back in the 80s or 90s, maybe even the early 2000s. Set in a dystopian future. A group of criminals, bandits or whatever, all males, numbering around 4-6. One member is needlessly violent. One is a young man or boy with retardation or some other mental handicap. I think he was the main character. The boy stops the group leader from killing the violent one at one point.
They break into a home where there's a small gap in the perimeter scanners of the home and this is where the incident of the boy stopping the violent one being killed occurs. I only read about 1/4-1/3 of the book, so I don't know how it ends or what the major story theme was. It was a full length novel, not a short story.
The setting was, I think, a wasteland with isolated pockets of modern technology. The home they break into was off by itself, I think. The book was recent or new when I read it.
I think the group leader wanted to kill the violent one because he had needlessly killed one of the people in the house they had invaded.

Back to page 1 with you.

Just brainstorming, maybe way off base, but could it be YA? Like something along the lines of one of the sequels to The Maze Runner or The Knife of Never Letting Go or even something like Margaret Peterson Haddix?

Can you remember anything about the bookcover? Anything will help

Cheryl, no, it isn't any of the Maze Runner books, The Knife of Never Letting Go or anything by Margaret Peterson Haddix. Thanks for trying.

Robert, no, I don't remember a thing about the cover.

Already posted there, but thanks for the suggestion.

I’m out of ideas. Have you tried wandering through the woods and seeing if you stumble across it?😂

No, but I might. ;-)

A hopeful bump.

I'll take a shot, I think it might be older..

Battlefield Earth
Dark is the Sun
Lucifer's Hammer
perhaps one of the Horseclan books where Milo remembers the past

The more I think about the more it seems familiar

The bit about “by a mostly mystery writer” keeps tripping me up. I was deep into mysteries throughout the 80s and 90s, but I haven’t read many since then. It’s hard to think of many who’ve crossed over into SF despite the readership moving between the genres.

Maybe someone like J.D. Robb (aka Nora Roberts)?

What’s the name of the mother-daughter team who write both mysteries and SF? Is it P.J. Tracy?

Sorry for forgetting to reply before, but it's none of your suggestions. Thanks for trying.

IIRC, mine was a lone house. I looked at Perry's stuff and nothing seemed familiar.

The Long Walk by any chance?

No, not The Long Walk. Thanks for trying.

Put the description into ChatGPT. See if that helps.

Didn't help. No results. Thanks for the suggestion.

Solved over at the PrintSF subreddit. It's Tom O'Bedlam by Robert Silverberg.

yay! Glad you finally got it figured!
