Translations for in fact in French

Here are paragraphs from public domain books translated:

“That is beyond dispute,” declared the inspector, whose excitement seemed to be nearing fever-point. “There is no question about it. All my investigations led to the same certainty. And my conviction gradually became so positive that I ended, one day, by drawing up this startling axiom: in theory and in fact, the robbery can only have been committed with the assistance of an accomplice staying in the house. Whereas there was no accomplice!”

— C’est un point indiscutable, affirma l’inspecteur, dont la fièvre semblait croître. Là-dessus, pas d’hésitation. Toutes mes recherches aboutissaient à la même certitude. Et ma conviction devenait peu à peu si grande que j’en arrivai un jour à formuler cet axiome ahurissant : « En théorie et en fait, le vol n’a pu être commis qu’avec l’aide d’un complice habitant l’hôtel. Or, il n’y a pas eu de complice.
