So, substitute a female version :o of A314, like MX102 or MX134, and you should get what you “want” to know. However, as was mentioned, you will possibly get more truth than you are “ready” for.
And, watch out for “self effects,” expecially if you get more truth than you expect. You may accidentally tell him more than you intend, too!
I don’t know people … there have been posts about people finding out things with its usage.
It may work, and it may not. Never hurts to try. 
Can you share what you’re trying to find out about? 
The good thing about telling the truth is … you never have to remember what you said.
You wanna find out if someone’s lying, ask the same question days later. Lies change, truth stays the same.

Find somebody who wouldn’t want to lie to you, because trust is important to them.
Sounds nice in principle but recollections of the human mind and truth are often not one in the same. The main diff is lies are deliberate falsehoods whereas truth is merely what you thought genuine. Either one may not be even remotely connected to reality.
