The peppered moth of the title is a famous example of evolution at work in industrial England. My understanding from the book is that there were formerly two colors of moths in a particular moth family, a light and a dark (the peppered one). The original theory was that during the Industrial Revolution the light colored moths moths evolved darker colors to suit the dark air caused by smoke, coal soot etc. Over time this theory was discredited to be replaced by a more rigorous one: that the lighter moths were easier prey in the dark air and thus became fewer in number. The darker ones, who were more difficult for predators to catch, survived to pass on the dark color genes to future generations of moths. However, The Peppered Moth is not about moths, although it is about evolution, family and in particular, three generations of women whose origins lie in a small northern England coal mining town, one where almost the entire town has been under-mined and there are frequent random cave-ins.
Two sisters are born here at the turn of the century, Bessie and Dora Bawtry, born into a coal mining family with few pretensions. Bessie is sickly, fair, slim, intelligent, yet disdainful of most people, especially her family. Dora is healthy, dark, round, conventional and adores her family. Our story intimately concerns Bessie's life and follows her through school, romance, university and marriage to her childhood sweetheart, Joe Barron. Marriage to Joe produces the second generation woman in our story, Chrissie Barron, a slightly wild, slightly willful daughter who dislikes her mother and adores her father. After leaving university to elope with gambling womanizer Nick Gaulden, Chrissie has her own daughter Faro, the third generation woman of our story. Faro is an intelligent, beautiful and successful science writer who now lives in London, remote from the dusty, dirty town of Bessie and Dora's youth. Our story opens when Great-aunt Dora and Faro attend a town meeting to contribute their DNA to a study undertaken to discover any local kinship to Cotterhall Man, an ancient skeleton recently unearthed in a nearby cave. Through Faro we are then led into her family's past: into Bessie's life, Chrissie's life and Faro's own life.
This description makes the book sound like an many-paged, multi-generational epic spanning the twentieth century and it could have been given all that happened in the twentieth century, but the book is remarkably succinct and not very long, for which I was grateful. The dominant character, Bessie, is not really very likeable but in the prologue we read that the book was the author's attempt to understand and describe her own mother, never an easy task. Understanding and insight into one's own family is difficult at best and the compassion we award to others, who are not our family, is often lacking. In the end however, this compassionate novel about survival, renewal and re-evaluation of feelings, relationships, and even environmentally degraded towns, concludes with both sympathetic understanding and hope for the future.
