Nancy Reynard, is the youngest of seven children. She is the seventh child of a seventh child. In fact, as both of her parents are seventh children, she is a seventh child twice over. She is the daughter of Colonel Septimus Reynard and his wife Blanche, and she lives very happily with her family at the Warren in Minchester until she reaches the age of ten, when she discovers that she has the gift of second sight; unfortunately, it is more of a nuisance and inconvenience for poor Nancy. She starts ‘seeing’ things, in particular things about her sister Blanche's new fiancé, and blurting them out for all and sundry to hear, much to his annoyance. And so begins Nancy’s career as a reluctant psychic detective. And now, no liar, thief or murderer is safe when she is near… or thousands of miles away.

Nancy is one of the earliest fictional psychic detectives, and she is unusual in being female and, when her gift makes its first appearance at least, just a child. A Seventh Child was first published in 1894. John Strange Winter was the pen name of the Victorian writer Henrietta Eliza Vaughan Stannard. This new edition includes an introductory essay by Gina R. Collia: 'John Strange Winter: Author, Wife, Mother & Purveyor of Toilet Preparations’.
