Woke this morning to devastating news. Our dearest friend Petra died suddenly yesterday. Petra, John and their family have been a significant part of our lives in latter years and Petra has provided me with unstinting love and support while going through my battle with lymphoma, having beaten the odds herself against breast cancer. The world will be a much poorer place without her. Our hearts go out to John, Helen, Liz and Michael, and the extended family.
