Rabbi David Small is the creation of author Harry Kemelman. He is the rabbi of a Conservative Jewish congregation in the fictional town of Barnard’s Crossing, Massachusetts. Small is a quiet, scholarly man who applies Talmudic reasoning and logic to solve murder cases that baffle the local police.
Small’s relationship with Police Chief Hugh Lanigan is central to the series. Lanigan, an Irish Catholic, develops a close friendship with the rabbi, and the two regularly discuss theology, philosophy, and crime over cups of tea. Each novel in the series is named for a day of the week, starting with Friday the Rabbi Slept Late.
