Translations for cleanliness in French

Here are paragraphs from public domain books translated:

One evening, as he was eating his dinner at a neighboring restaurant, a man entered and took a seat at the same table. He was a person about forty years of age, and wore a frock-coat of doubtful cleanliness. He ordered soup, vegetables, and a bottle of wine. After he had finished his soup, he turned his eyes on Danegre, and gazed at him intently. Danegre winced. He was certain that this was one of the men who had been following him for several weeks. What did he want? Danegre tried to rise, but failed. His limbs refused to support him. The man poured himself a glass of wine, and then filled Danegre's glass. The man raised his glass, and said:

Un soir qu’il dînait chez un traiteur du quartier, quelqu’un s’installa en face de lui. C’était un individu d’une quarantaine d’années, vêtu d’une redingote noire de propreté douteuse. Il commanda une soupe, des légumes et un litre de vin. Et quand il eut mangé la soupe, il tourna les yeux vers Danègre et le regarda longuement. Danègre pâlit. Pour sûr cet individu était de ceux qui le suivaient depuis des semaines. Que lui voulait-il ? Danègre essaya de se lever. Il ne le put. Ses jambes chancelaient sous lui. L’homme se versa un verre de vin et emplit le verre de Danègre.
