Who brings Paul news about his mother? What is the news?

From the text:

Because I have already had a long leave I get none on Sundays. So the last Sunday before I go back to the front my father and eldest sister come over to see me. All day we sit in the Soldiers' Home. Where else could we go? we don't want to stay in the camp. About midday we go for a stroll on the moors.

The hours are a torture; we do not know what to talk about, so we speak of my mother's illness. It is now definitely cancer, she is already in the hospital and will be operated on shortly. The doctors hope she will recover, but we have never heard of cancer being cured.

"Where is she then?" I ask.

"In the Luisa Hospital," says my father.
