Agatha Christie bought the property in the 1930's by which time she was an established writer with a good income. The house was bought for £6,000 and was one that she and her mother had coveted many years before.
During her time owning Greenway, it was used for holidays including summer and Christmas and she and her husband undertook a number of improvements to the property.
He enjoyment of the Greenway was interrupted by the Second World War when the property was requisitioned by the Government. Members of the US costaguard were billeted in the house and left their mark in the form a mural in the library which appears to relate their experiences in the War.
