Two sisters conduct a modern-day investigation into a Victorian-era murder of a toddler and discover their grandmother was a key witness.

While researching her ancestry on the Internet one gloomy evening, Penny is astonished by what she finds. Urgently, she instructs her sister Sheelagh, "Search 'Slaidburn Suspected Child Murder!' Now!" So begins a remarkable story within a story spanning more than a century.

In 1885 Yorkshire, sisters Grace and Isabella, accused of murdering Grace's secret illegitimate toddler, were on trial for their lives. A sadly neglected two-year-old boy was dead following a failed attempt to lodge him at a workhouse. A tense and sensational trial followed in Victorian-era Leeds.

Sheelagh and Penny began keenly re-investigating these events. They feel personally involved because a prosecution witness at the murder trial, nine-year-old Margaret Isherwood, would later become their grandmother. The book grips us with dramatic events, but also touches us with the abiding loyalty of sisterhood, the desperate power of our need for love, and the crazy things that it can make us do.
