Synonym for a word meaning 'unreliable narrator'?

Question

It's somewhere in my notes, but I can't find it..also, I have to mention it a few times, so synonyms would help.

thanks.

Answer 1

Unreliable narrator as in unreliable speaker?

How about a liar or prevaricator?  Untrustworthy?  A wolf in sheeps' clothing?

I have heard someone unreliable called a frail reed, although that is unusual.  You might work in something like - don't hold your breath waiting for what he says to come true; what he says is like fools' gold.

I hope that helps.
