"a sort of fundamental implausibility"

Adrian Scarborough (The BBC)

     "It would be a travesty to say that Guy suspected Apthorpe of lying.  His claims to distinction—porpoise-skin boots, a High Church aunt in Tunbridge Wells, a friend who was on good terms with gorillas—were not what an imposter would invent in order to impress.  Yet there was about Apthorpe a sort of fundamental implausibility."
