To all that, I didn’t say a word. I would look up sometimes as he spoke and catch her glance, witnessing my unspoken exasperation, and then her demure smile. There was some irony. I was the older man.

She met me when I had all those labels. Or she could twist a few degrees and see the labels on Madox. Yet apart from the Geographical Society we were unknown; we were the thin edge of a cult she had stumbled onto because of this marriage.

The words of her husband in praise of her meant nothing. But I am a man whose life in many ways, even as an explorer, has been governed by words. By rumours and legends. Charted things. Shards written down. The tact of words. In the desert to repeat something would be to fling more water into the earth. Here nuance took you a hundred miles.
