Her most personal book, Celebration, came out in 1989, shortly before Bridget died at 22. It is a tough, clear meditation on illness and suffering in the light of her faith in God. Margaret itemised without flinching the cruelties she had discovered in creation, in her daughter’s life and on the wards at Great Ormond Street, where she once reached out to stroke a crying child’s face and was stopped by a nurse who told her that the slightest touch could break the child’s bones. She could reconcile none of these things with the idea of a loving and benevolent God and she made no attempt to do so. Instead, she was convinced that God shared in the sufferings of his creation and that through the symbolic recreation of Jesus’s acceptance of death in the eucharist it could somehow, sometimes, be made bearable.
