Daisymead (The King of Clubs)

In the short story The King of Clubs, Daisymead is the home of the Oglander family, in Streatham. Although it is near the crime scene, the mansion of Henry Reedburn, Mon Désir, it is not the nearest place where one could go to for help. Indeed it is only visible from one place of Mon Désir. This would be a material fact in helping Poirot solve the case.
