Hi,I'm confused with your use of "the man" with the plural possessive "their" in the first sentence.
"The man wasn't expecting anything today, just as previous days had led to nothing on their search."
It seems like it should say "his search." The second sentence does the same thing, beginning with "they" as though referring to a group of people, then going to Howard.
The "solitude of the norm" was a hiccup for me, others may feel differently but I had to read it again to get a clear understanding of what you meant.
In the following:
"Howard was a middle aged man, he was in his late forties and was six feet tall exactly, had hair that was starting to show some gray under his brown, combed over hair."
You tell us that he's middle-aged and then say that he's in his late forties which seems a bit repetitive. Also, this sentence sounds (to borrow a word from someone who recently used it to critique my work) infodumpy. It's like you want to give us an exact description of him so instead of revealing it in the story you tell us all at once. Another section:
"Calling him by his name was considered rude where he was from, but he did not mind if Thomas did . . . "
This made me stumble a bit, too because I thought you were referring to Howard. Perhaps you could clarify who you are talking about earlier in the sentence, maybe you could say, "Calling the 'helper' by his name was rude, but . . . " That sentence also seems like it's several sentences lumped together by the word, "so." It might read more smoothly if you broke it up into two or three.
I am curious to know what the has to do with any of this and what they're looking for. I do hope that this helps you a little bit.
