The second book of Florence Nightingale's life covers the period just before she traveled to the Crimea War. The historical facts were well research and accurate. Florence is called to the household of Sidney Herbert as her friend Helen and her father were shot at on there way for a visit to a museum. The occupants of the carriage were not hurt but the coachman died. Sidney asked Florence to investigate. One of the upper servants of the Herbert Household dies at Florence's hospital from cholera. The inquiry into the affair takes Florence into deep into Soho slums. I like the method that the physicians went about establishing the cause of the Cholera tracing it to a dipper rinse in a closeby area. Previous to that event happening cholera was thought to be from the air and not from the water. I highly recommend this book and series.
