man might say something compromising to him in my presence? It looked
rather like it. And yet he had gone away and left me with the patient
and the housekeeper.

But when I came to think about it I remembered that Mrs. Schallibaum had
shown some anxiety to prevent the patient from talking. She had
interrupted him more than once, and had on two occasions broken in when
he seemed to be about to ask me some question. I was "mistaken" about
something. What was that something that he wanted to tell me?

It had struck me as singular that there should be no coffee in the
house, but a sufficiency of tea. Germans are not usually tea-drinkers
