What it means
You're interested in what people hide: motives, secrets, investigations, psychology. The person you're talking to feels seen through. You say little, but precisely, sometimes sharply.
The flip side is suspicion and sarcasm; it's hard to take anyone at their word, and you keep your thoughts to yourself.
This isn't about you if you believe people at their word and detectives and other people's motives don't interest you.
