David Horovitch

David Horovitch (born 11 August 1945) is an English actor, perhaps best known for playing the character of Inspector Slack in Miss Marple. He stars in the Game of Thrones prequel series House of the Dragon as Grand Maester Mellos.
Horovitch was born in London, the son of Alice Mary, a teacher, and Morris Horovitch, a child care worker. He was educated at St Christopher School, a boarding independent school in the town of Letchworth Garden City in Hertfordshire, followed by the Central School of Speech and Drama in London.
Horovitch's father was Jewish but atheist and married a non-Jew, and Horovitch was not brought up in the faith. He was in his 40s when he was given a string of Jewish roles and started learning about the religion.
