“I cannot remember who scored runs or took wickets, and I have always held in check the temptation to take an archaeological dig into Wisden to find out. Long ago I realised that to go looking for the evidence risked shaking loose the memories I already had; and possibly losing some of them as a consequence. So the important fragments of that day remain intact, shut and airtight in my mind, as if sealed in a jar. The scorecard my grandfather bought me - and filled in with a silver ballpoint pen - is long gone too. I have nothing that preserves our time together there except for the dozen or so still, square images which I can slide in a private show across my mind. These keep alive its broad outline, which is sufficient. The bold statistics don't matter anyway. What does matter is the imprint our journey to Trent Bridge left on me. It's evident in this book, which is also part-payment of an outstanding debt to my grandfather which I can never fully repay.”
