Every mystery is the same at its heart. Someone is murdered, something is stolen and the enterprising sleuth has to solve the mystery. The way to make an interesting mystery is to have well-developed, well-written characters that the reader cares for. No one does this better than the queen of mystery, Agatha Christie. From the lovable adventuress Anne Bedingfield to her society lady patron Suzanne to her love interest Harry, every character is amazingly thought out and provokes such care for each and every one of them in the heart of the reader.
