Translations for maiden in French

Here are paragraphs from public domain books translated:
Sherlock Holmes sat silent for a few minutes with his fingertips still pressed together, his legs stretched out in front of him, and his gaze directed upward to the ceiling. Then he took down from the rack the old and oily clay pipe, which was to him as a counsellor, and, having lit it, he leaned back in his chair, with the thick blue cloud-wreaths spinning up from him, and a look of infinite languor in his face. "Quite an interesting study, that maiden," he observed. "I found her more interesting than her little problem, which, by the way, is rather a trite one. You will find parallel cases, if you consult my index, in Andover in '77, and there was something of the sort at The Hague last year. Old as is the idea, however, there were one or two details which were new to me. But the maiden herself was most instructive." Sherlock Holmes demeura quelques instants silencieux, les doigts serrés, les jambes étendues, le regard obstinément fixé au plafond. Puis il décrocha de son chevalet la vieille pipe de terre huileuse qui était en tout temps sa conseillère et l’ayant allumée il se renversa sur sa chaise. Bientôt un nuage de fumée l’enveloppa tandis que son visage reflétait une langueur extrême. — Le problème est banal, observa Holmes, mais la jeune personne est intéressante à étudier. J’ai déjà vu des cas semblables ; mon recueil fait mention d’une circonstance analogue à Andover en 77. L’année dernière même, à La Haye, il s’est passé une chose similaire, et, quelque ancienne que soit la ruse, j’ai noté ici cependant deux détails absolument inédits. Mais la jeune fille à elle seule est une étude.

“They had gone a mile or two when they passed one of the night shepherds upon the moorlands, and they cried to him to know if he had seen the hunt. And the man, as the story goes, was so crazed with fear that he could scarce speak, but at last he said that he had indeed seen the unhappy maiden, with the hounds upon her track. ‘But I have seen more than that,’ said he, ‘for Hugo Baskerville passed me upon his black mare, and there ran mute behind him such a hound of hell as God forbid should ever be at my heels.’ « Les amis de Hugo galopaient depuis deux kilomètres, quand ils rencontrèrent un berger qui faisait paître son troupeau sur la lande. En passant, ils lui crièrent s’il avait vu la bête de chasse. On raconte que la peur empêcha l’homme de répondre immédiatement. Cependant il finit par dire qu’il avait aperçu l’infortunée jeune fille poursuivie par les chiens. « — J’ai vu plus que cela, ajouta-t-il ; j’ai vu galoper en silence, sur les talons du sire de Baskerville, un grand chien noir, que je prie le ciel de ne jamais découpler sur moi. »
