It's remarkable how far iconic images travel. Yesterday morning I was in Liege, Belgium. In front of me, a hill of flowers and candles - a growing tribute to the two little girls found dead the previous day after an exhausting - and exhaustive - three-week search.
I started talking to one woman - tears in her eyes, her own little girl hugged up against her shoulder - who told me "now we have our own Holly and Jessica". She was referring, of course, to the Soham case - Holly Wells and Jessica Chapman. "I remember them in their football shirts" she said, "Manchester United."
And there you have it. The most disturbing British crime story in a decade, boiled down to one image, as recalled four years later on a Belgian country lane.
