Shroud for a Nightingale (1984 ​ - 1984)

Adam Dalgliesh is on the trail of alleged international arms dealer Martin Dettinger - a man with distinctly dubious Eastern European connections and who may have been responsible for the death of an important witness. Seriously ill, Dettinger books himself into the John Carpendar Hospital for vital heart surgery - and then student nurses begin to die. The first is murdered right in front of Adam Dalgliesh.
