Mrs Templeton (The Terrible Catastrophe)

In the short story The Terrible Catastrophe, (later chapter 15 of The Big Four), Mrs Templeton was the wife of Mr Templeton, an elderly gentleman who lived with his family at his house, Elmstead, in Hertfordshire. Mr Templeton is an invalid who has repeated bouts of gastric attacks. His Nurse Mabel Palmer suspects he is being poisoned as she had seen Mrs Templeton with the attending physician Dr Treves in the garden together.

Note: There are two Mrs Templetons in Christie's works. The other occurs in Why Didn't They Ask Evans?.
