Agatha Christie Wiki

In the novel The Hollow, 404 Harley Street is the house and clinic of Dr John Christow. He lived there with his family. Christow's parents had been "Anglo-Indians", suggesting that they had been overseas most of the time. He had grown up "bandied from aunt to uncle". The Harley Street house was his first permanent residence but somehow he did not think of it as home.
