Pretty effective and creepy, though if I were to be a rule weasel, I’d point out that the line of action provided new information about the characters (specific ages). Such a weasel.
The pungent scent of bubblegum mixed with sweat made for a visceral read. Again, this is creepy, but its told well enough to be that way.
It would be improved a great deal by less detail. “Bubblegum and sweat” and the single quote are more than enough to get the point across, everything else is superfluous. Telling your audience more than you have to robs the piece of it’s potential.
Watch the opening sequence of Fritz Lang’s “M”. I’d recommend the whole thing, but the opening is what applies here. Nothing is explicit, but the point is made strong and clear.
JMV – Thanks. (Of course, if I leave out the action, that loses the challenge.) I’ve seen something of M, but haven’t yet watched the whole thing. Might make a special search for it now.
I tend to agree that less would be more here although I sometimes lean so far toward minimalist I just publish blank pages, so take my suggestions with a truckload of salt.
I’d be tempted to cut out “the man” and have just “him”, giving—"eddied lazily around him." I figure we’re not going to learn anything more about this guy so why not just make it ‘him’, reduce him to three letters and a totally impersonal personal pronoun?
And then, as jesteram has already said, the ages aren’t necessary. I’d go so far as to say “little girl” isn’t either. The mood is unsettling and the less the reader has to hold onto, the more those clever atmospherics (the blend of smells) stand out and become something to clutch at.
OK, so I’m reading the nicely edited version – and I think it’s suitably creepy and well-written. And I like the ambiguity; we’re not sure whether the bubble gum is his or the kid’s. Very ominous.
