I knew that on the island one was driven back into the past

I did one other thing that week. I wrote a letter to Alison. I sent it inside an envelope addressed to Ann in the flat below in Russell Square, asking her to post it on to wherever Alison was living. I said almost nothing in the letter; only that Id thought about her once or twice, that I had discovered what the waiting room meant; and that she was to write back only if she really wanted to, Id quite understand if she didnt. I knew that on the island one was driven back into the past. There was so much space, so much silence, so few meetings that one too easily saw out of the present and then the past seemed ten times closer than it was. It was likely that Alison hadnt given me a thought for weeks, and that she had had half a dozen more affaires. So I posted the letter rather as one throws a message in a bottle into the sea. Not as a joke, perhaps, but almost; yet with a kind of ashamed hope.
