Anemia signifies a decrease in the number of circulating red blood cells.

A few years ago a 19-month-old girl was taken to Hammersmith Hospital in London.
She was semiconscious. The doctors examined her carefully and could not find out what was wrong with her.
Soon she became much worse and the doctors thought she would die.
Then one of the nurses who was looking after the little girl suggested to the doctors that she might have thallium poisoning. She told them that she had just read a detective story by Agatha Christie called ‘A Pale Horse’. In this story there was a description of a person who was dying of thallium poisoning. The nurse told the doctors that the way that the girl was behaving was very like the way that the poisoned person in the detective story behaved. She showed the same symptoms as the little girl.
The doctors sent some of the little girl’s blood to the laboratory and asked them to test it for thallium.
The laboratory tests showed that in the girl’s blood there was more than ten times the safe amount of thallium.
The doctors were now able to do something for the child, and four months later she was cured.
And all because the nurse had been reading a detective story by Agatha Christie.
