The Blue Diamond - A beautiful young woman, who seems to have lost her memory, is found wandering in Sir Arthur Hargreaves' estate. But soon, the nurse who's supposed to be in-charge of her and knows her real self is reported missing. The police are called in and they suspect that there is a link between the nurse's disappearance and the legend of the valuable family diamond. Will Sir Arthur ever get to know the truth? Will the family diamond ever return to its rightful owner... Annie Haynes (1865-1929) was a renowned golden age mystery writer and a contemporary of Agatha Christie, another famous crime writer, which often led to her comparison with the latter, and unfavourably so. Haynes's fictions are now lauded for their quick-pace action and sustaining aura of suspense, till the end.
