The Reverend Mother’s investigative skills are called into action when a local tobacco factory burns down and fingers are pointed at one of her ex pupils…

1920s. Cork, Ireland. Early one morning the Reverend Mother receives news of a deadly fire at the local cigarette factory, a place where she’d been so proud that some of her pupils had been given a steady job. In a city full of poverty, unemployment and political unrest, these ex pupils of hers had surely been blessed with such prospects. Now, though, she is worried . . . What happened at the cigarette factory and why are there rumours circulating that one of her ‘girls’ was responsible?

Inspector Patrick Cashman is under pressure to quickly find the cause of the fire – and identify a suspect – to placate the visiting Lord Mayor and Commissioner and secure his hopes of promotion. Patrick turns to his friend, the journalist and law student Eileen MacSweeney for help, along with the ever insightful and calm Reverend Mother. From the fog-ridden streets of the slums to the green pastures and prosperity of nearby Youghal, together they begin to unravel a seedy history of greed, ambition and a desire for power.
