I've never tried this, and it probably would not work. I don't think I'd even attempt it. However! A trick to detect a lie or fabrication is to have someone go through something in reverse chronological order. People usually have trouble constructing a false narrative in reverse.
Common police tactic to test the authenticity of a witness/suspect's story.
Another tactic is to leave the topic for a while - go completely off course - and then ask the candidate to write it down in front of them. The act of writing, instead of speaking, adds to the difficulty if the story is false.
