Lord Edgar Blackwood, head of the prominent Blackwood Group, was an old-fashioned man who favored sons over daughters. He triedΒ to use his young granddaughter, Cassandra Blackwoodβs kidneys to save her twin brother, Christopher's life. However, their mother, Diana Greene, arranged for Cassandra to be taken away to safety. The doctor who helped escape hid Cassandra in a garbage dump to protect her. Fortunately, she was found and taken in by Frank Burton and his wife.
