Women in intimidating hats glared at him with revulsion.

Even the guy who sang that song about how much the Grinch sucked didn't go on this long! And he really let that jerk have it.
I suppose the point isn't what Lew did. I think the point is that anybody can lose their reputation as long as a certain amount of people will buy into it. It's like that episode of Black Mirror where the main character's social media rating tanks in one crappy day and pretty soon everybody thinks they're the worst person in the world. Lew either did something so incredibly shitty he deserves to be an outcast or he simply pissed off the wrong person with all the right contacts.
But how all of this answers the question about how he became a detective, I don't know! Maybe it's common knowledge that detectives become detectives because they're unsavory, unlikable jerks? I hope I don't have to have any knowledge of noir pop culture because I don't have any.
"Women in intimidating hats"
I can only imagine this means big, ornate hats with loads of feathers and other dingle-boppers. I doubt it means hats with spikes and cleavers hanging from the rim.
