On day one of the main draw action at Indian Wells, two-time Wimbledon champion Petra Kvitova was beaten 4-6 6-3 6-4 by France's Varvara Gracheva.

Two decades after a devastating tsunami swept across Southeast Asia, Petra Nemcova is recalling what, and who, helped her survive the storm.

In the Hertfordshire town of Letchworth, a woman called Petra told me how an NHS social worker called Margaret Falegan had brought Mr Hiller to her house during a professional visit.

Petra suffers from anxiety and had previously told Ms Falegan - whom she described as her mental health nurse - that she was having trouble with her bills.

Whatever Mr Hiller had meant by this, Petra read it as a threat.
