Edith (Third Girl)

In the novel Third Girl, Edith is the maid of Ariadne Oliver. In the middle of the novel, she called George and asked him to relay a message to Poirot to the effect that Ariadne had been admitted to St Giles's Hospital after someone had hit her on the head. George did not pass on the later part of the message, where Edith had remarked that it is all Poirot's fault.
