Memories surface after an old friend reappears; an excerpt from Rahman's forthcoming novel.
All the same, it is not guilt alone that brings me to my desk to put pen to paper and reckon with Zafar’s story, my role and our friendship. Rather, it is something that no single word can begin to describe but which, I hope, will take form as I carry on. All this is quite fitting really – how it ought to be – when I call to mind the subject of my friend’s long-standing obsession. Described as the greatest mathematical discovery of the last century, it is a theorem with the simple message that the farthest reaches of what we can ever know fall short of the limits of what is true, even in mathematics. In a sense, then, I have sat down to venture somewhere undiscovered, without the certainty that it is discoverable."
