Student or Learner
I have a question.
This is a discription about a bad guy in a novel. He is a detective,
but is really corrupted.
"He comes in real unassuming, but he kicks it up 10 notches every time."
Does "notch" here mean "point"?
Does this sentence mean he appears humbly, but does things to beat
someone effectively every time"?
Thank you very much for your kind explanation about the sentence
and "notch" itself.
And thank you for correcting my misspelling and grammar.
I really appreciate it.
