Translations for harmless in French

Here are paragraphs from public domain books translated:

Her only reply was a gesture indicating that she was afraid of our companion. I smiled, as her husband had done, shrugged my shoulders, and explained to her, in pantomime, that she had nothing to fear, that I was there, and, besides, the gentleman appeared to be a very harmless individual. At that moment, he turned toward us, scrutinized both of us from head to foot, then settled down in his corner and paid us no more attention.

Sans me répondre, elle me désigna d’un geste craintif l’individu. Je souris comme avait fait son mari, haussai les épaules et lui expliquai par signes qu’elle n’avait rien à redouter, que j’étais là, et d’ailleurs que ce monsieur semblait bien inoffensif. À cet instant, il se tourna vers nous, l’un après l’autre nous considéra des pieds à la tête, puis se renfonça dans son coin et ne bougea plus.
