The Naked Sun by Isaac Asimov

Detective Elijah Baley is sent from Earth to the distant planet Solaria, where human contact is virtually non-existent and society is run completely by robots.
Elijah is partnered with (Robot) Daneel Olivaw, to solve a major Solarian scientist's surprising murder - an unprecedented crime in a culture where people interact almost entirely through holographic "viewing" instead of face to face. As Baley navigates the harsh social customs of Solaria and his own agoraphobia, he highlights the mysteries that challenge the delicate balance between humanity and its machines, questions about the human need for separation, dependence and connection.
Somehow, Asimov foresaw the lack of physical contact coming even in the age of black and white television sets.
