The author was Agatha Christie, a gentle married lady and one of the most successful writers of detective stories in the world. ks5u In June 1977 , a baby girl became seriously ill in Qatar   , near Sandi Arabia  . Doctors were unable to find out the cause of her illness, so she was flown to London and sent to Hammersmith Hospital. A team of doctors hurried to examine the baby only to discover that they, too, were puzzled by the very unusual signs of illness. While they were having a discussion about the baby's illness, a nurse asked to speak to them.  "Excuse me," said Nurse Marsha Maitland, "but I think the baby is suffering from thallium poisoning  ." "What makes you think that?" Dr. Brown asked. "Thallium poisoning is very rare." "A few days ago, I was reading a novel called 'A Pale Horse' by Agatha Christie," Nurse Maitland explained. "In the book, somebody uses thallium poison, and all the signs are exactly the same as the baby' s . " "You are very careful and you may be right," another doctor said. "we'll carry out some tests and find out whether it' s thallium  or not." Tests showed that the baby had indeed been poisoned by thallium.
