Translations for patron in French

Here are paragraphs from public domain books translated:

"Well, when I came to think it all over in cool blood I was very much astonished, as you may both think, at this sudden commission which had been intrusted to me. On the one hand, of course, I was glad, for the fee was at least tenfold what I should have asked had I set a price upon my own services, and it was possible that this order might lead to other ones. On the other hand, the face and manner of my patron had made an unpleasant impression upon me, and I could not think that his explanation of the fuller's-earth was sufficient to explain the necessity for my coming at midnight, and his extreme anxiety lest I should tell any one of my errand. However, I threw all fears to the winds, ate a hearty supper, drove to Paddington, and started off, having obeyed to the letter the injunction as to holding my tongue.

Lorsque j’eus repris mon sang-froid et que j’eus bien réfléchi à tout cela je trouvai très étrange le genre de travail qu’on me proposait ainsi. D’un côté, j’étais assez satisfait, car les honoraires étaient dix fois supérieurs à ceux que j’aurais pu demander, et cette commande pouvait m’en amener d’autres. Mais, de l’autre côté, le visage et les manières de mon client m’avaient fait mauvaise impression, et je ne pouvais trouver dans son histoire de terre à foulon une explication suffisante à un voyage nocturne ni à un secret aussi absolu. Enfin, je mis de côté mes appréhensions ; je dînai de bon appétit, et je m’embarquai à Paddington, sans avoir dévoilé quoi que ce soit de mon secret.
