They said it got so cold the water condensed in the air, and it was like the whole hospital was right under a shower bath. Everybody on the top floor had to e down because it rained right on their beds, and for two nights I had a man in my room with me that had his arm cut off in a machine. But we couldn39。t always get dark here, Diane said. Sometimes the rain sparkles. I think Dr. Island must do it to cheer everyone up.

He was married five years, had three children, lost most of the fifty thousand dollars his father left him, the balance of the estate having gone to his mother, hardened into a rather unattractive mould under domestic unhappiness with a rich
