A whimsical expedition across the Turkish landscape spirals into a complex exploration of faith, memory, and the absurdity of human conviction. The narrator, Laurie, accompanies her eccentric Aunt Dot and a clergyman on a journey from Istanbul toward the legendary city of Trebizond. Their progress is hindered by bureaucratic incompetence, local sorcery, and the surreal intrusion of American evangelists. The narrative unfolds through a witty, first-person perspective that balances comedic observation with the weight of a clandestine, unrequited love.

This novel is widely regarded as a pinnacle of mid-century English satire, celebrated for its unique blend of sharp wit and underlying emotional gravity. Critics frequently highlight Macaulay's ability to juxtapose the ridiculousness of her characters' circumstances with the genuine, often painful, interior life of the narrator. The work is often cited for its stylistic elegance and its refusal to offer easy resolutions to the complex questions of faith it poses. Readers often find the interplay between the comedic travel narrative and the narrator's private heartbreak to be both unexpected and deeply resonant. The book remains a staple of literary discussions regarding the intersection of travel writing and the novel form.
