Greeta was magnificent. She had such presence, such dedication and such compassion. When I first met her in Kolkata 10 years ago, I went out with her on a night patrol, where she visited the most vulnerable families and children living on the streets, she knew so many of them by name, the young mum who'd just had a baby, living in an underpass, the children she was particularly worried about and may need to bring into care. In the teeming slums she showed me that everyone is an individual with hopes and ambitions. Geeta was a force of nature, she changed so many lives and legacy will be immense. It is heartbreaking that she was taken from us far too soon.
