so would the steal and know void classes be good with forensics and detective stuff in general ? as they steal/know all the secrets, and since forensics and detective stuff is all about obfuscation of knowledge and secrets wouldn't they be simply the best

I feel with the right Aspect, you could have good detective and forensic stuff with nearly any Class. Even then, I feel if you just stretch it a liiittle bit, you could have virtually anyone being good with that stuff. Like a Mind Player could think like a criminal and sort of be a step ahead, or a Light Player may shed some metaphorical light on a case that’s been cold for a long time, it all depends on the spin you give.
