Just lately it seems that every time you tune in to the news there is yet another massacre or atrocity resulting in injury and loss of life. Now it is Nice's turn. When will all the killing stop? Recently on holiday in Cornwall I came across this box hidden in the wall outside the local church, where you can post a prayer. I am not an openly religious person but if ever there was a time for prayer it would be now and this box I suspect might be full today.
