Alexandros Papadiamantis (1851–1911) was born and raised on the Aegean island of Skiathos, the setting not only of The Murderess but of many of his short stories, literary sketches, and novels. His mother was a descendent of an established local family and his father was a Greek Orthodox priest. As a young man, Papadiamantis spent seven months in a monastery and studied philosophy at the University of Athens before taking up a career as a journalist and translator. He enjoyed popular success as the author of historical adventure novels like The Gypsy Girl (1884), which were serialized in daily newspapers, but it was not until he turned to writing short stories and novellas that he gained critical recognition. Though a heavy drinker and smoker, Papadiamantis was devout, poor, and solitary, known as the saint of modern Greek literature. He lived in Athens rooming houses until 1908, when he returned to Skiathos. Two years later, he died of pneumonia.

Peter Levi (1931–2000) was a poet, translator, novelist, and professor of classics at Oxford. Educated at Catholic schools, he was ordained as a priest in 1964 and remained one until 1977. He wrote more than twenty volumes of poetry, and from 1984 to 1989 held the chair of Professor of Poetry at Oxford.
