EosJupiter,

I see little basis for accusing MrAugust of being a polygraph examiner. I think it's perfectly understandable that someone who suspects his wife has been unfaithful might be eager for something -- anything -- that would offer some degree of confidence in the matter. Polygraphers profess to offer a high degree of confidence in situations where ascertaining the truth is difficult or even impossible. (After all who can truly prove that s/he has not been unfaithful to his/her spouse? One cannot prove the negative.) I don't find it surprising that someone in MrAugust's difficult situation might look to polygraphy or some other pseudoscience (such as voice stress "testing") for answers. Such wishful thinking ensures polygraphers a steady stream of customers.
