Translations for falsehood in French

Here are paragraphs from public domain books translated:

Aramis appeared to make a strong inward effort, like a man who, in the full relation of a falsehood, finds himself stopped by some unforeseen obstacle; but the eyes of his three companions were fixed upon him, their ears were wide open, and there were no means of retreat.	Aramis parut faire un effort sur lui-même, comme un homme qui, en plein courant de mensonge, se voit arrêter par quelque obstacle imprévu ; mais les yeux de ses trois compagnons étaient fixés sur lui, leurs oreilles attendaient béantes, il n’y avait pas moyen de reculer.
