The best-known supernatural works of Margery Lawrence include Number Seven, Queer Street, a collection that collects the case histories of an occult detective, Dr Miles Pennoyer, as related by his assistant Jerome Latimer. Lawrence stated that this series was inspired by Algernon Blackwood’s John Silence stories and Dion Fortune’s Dr. Taverner series. Like May Sinclair before her, Lawrence became a confirmed spiritualist and believer in reincarnation in later years. According to the author, “My interest in it dates actually from the moment when I saw a near relation three nights after he died, when he gave me specific instructions about the finding of a box containing important papers. They were found precisely where he said–and from that moment I became deeply interested in what…I have called the “Other Side.” Somewhere that man was obviously still alive! Somewhere he was thinking of us, anxious to help, caring what happened; in a word, he was still alive somewhere, and I was determined to find out where.“
