Lidia was a real person:

Lidia Poët (1855 – 1949) was the first modern female Italian lawyer. Her disbarring led to a movement to allow women to practice law and hold public office in Italy. - Wikipedia

In the show she is a cute, bright pixie, member of a wealthy family. I mean we don't really care about the peasants do we? She's basically a 19th century Nancy Drew, using her wits to solve a murder in each episode, and or course exonerating the falsely charged fool who has gotten arrested.

19th century technology is in evidence: she has a typewriter, she trades a priceless Ming vase for a bicycle, the concept of using fingerprints to identify a person is known, though not commonly accepted. And the prosecutor's office has a volumetric glove, which is basically a mechanical lie detector.

The first scientific lie detector test was invented by Cesare Lombrosso in 1895. This was known as the Volumetric Glove. The subject's hand was placed in a container of water. The amount of water displaced as the subject was asked questions indicated peripheral vasoconstriction, and thus the amount of stress present. - Polygraph Solutions

Cesare Lombroso, a famed criminologist, described a primitive lie detector called a volumetric glove in his 1876 book Criminal Man: "The glove is filled with air, and the greater or smaller the pressure exercised on the air by the pulsation of the blood in the veins of the hand acts on an aerial column. . . . [T]his chamber supports a lever carrying an indicator which rises and falls with the greater or slighter flow of blood in the hand." - Chegg

Mosso was encouraged in his studies of the emotions by Lombroso, his tutor and contemporary. His work is of unusual interest to the student of deception, particularly his studies of fear and of its influence on the heart and respiration. As early as 1875 Mosso demonstrated, by means of a "plethysmograph" (an instrument for measuring blood pressure and pulse changes) periodic undulations in man's blood pressure caused by the respiration cycle; " and his ingenuous studies of the circulation of the blood in the brain opened up new avenues for the study of the influences of fear. In 1895 he described a new device for measuring blood pressure, giving credit to Vierordt for first measuring man's blood pressure, from the outside, in 1855. - Journal of Criminal Law and Criminology

The device in the show is a mechanical device that holds the subject's wrist and records the changes in pressure on a black tape that also runs through the device.
