From PBS Streaming:

A student of Sigmund Freud and an Austrian detective team up to solve some of the most mysterious and deadly cases in early 1900s Vienna.

From PBS Masterpiece Streaming you can watch 6 episodes, each lasting about 45 minutes.  Each of the three stories encompasses 2 episodes.

Changes were happening in 1900s Vienna.   Oskar Reinhardt is an Austrian detective who, when the series begins, is used to old-school methods that can involve using violence against suspects.  Little by little he adapts to using the newer methods of Max Liebermann. Max is a doctor working in a hospital run by a bully that is fond of using electrotherapy.  Max, as a student of Sigmund Freud, is more attuned to using psychological methods for understanding and curing his patients.

One important theme is Vienna’s virulent  antisemitism.  Max is the eldest son of an observant Jewish family.  As a subplot, Max is engaged to one woman (a Jewess) but falls in love with one of his patients (a gentile) whom he cured using Freudian methods.

Oskar is in constant mourning over the death of his young daughter. As a result his wife has at least temporarily left him.

In each of the 3 murder cases, Oskar stands fast against the prejudices and rush to judgement of his superiors.  Similarly Max stands fast against the malpractice of his own superiors.

Be at least warned that the third story leaves a bitter taste in the mouth.

Old-fashioned and well-done drama.
