Dalgliesh

Set in 1982, Series 4 brings three new labyrinthine cases for Commander Adam Dalgliesh to untangle with the help of his colleague DI Clive Roscoe.

The first instalment, A Mind to Murder, follows the killing of an officious administrator in an experimental private psychiatric clinic, which puts each of her colleagues in the spotlight and draws light on the questionable treatment of patients.

In Original Sin, the mysterious death of an upstart publisher leads to the unravelling of a decades-old mystery, full of dark revenge and heartache.

In the final instalment, Dalgliesh investigates the murder of an ex-inmate at a women’s prison in London, where the murder draws attention to her aristocratic cell mate and reignites questions about a highly publicised murder trial.
