Shroud for a Nightingale (Adam Dalgliesh Mystery Series #4)

The young women of Nightingale House are there to learn to nurse and comfort the suffering. But when one of the students plays patient in a demonstration of nursing skills, she is horribly, brutally killed. Another student dies equally mysteriously, and it is up to Adam Dalgliesh of Scotland Yard to unmask a killer who has decided to prescribe murder as the cure for all ills.

The New York Times called Shroud for a Nightingale "mystery at its best."
