To James and David. I worked with Fiona to understand how to fight Covid. We spoke only few times, but I have been deeply touched by her wonderful soul. She spoke of you, and her huge smile filled the space. My heart is so broken, I cannot... think. My mother took her life few years ago. There is nothing that can be said, nor anything that is useful to hear. But in sadness, you are not alone. Ignazio Maria Viola.
