The Mysterious Mr. Quin

In this 1930 collection of twelve short stories, Mr. Satterthwaite—a quiet observer of society—keeps stumbling into puzzles that refuse to stay buried.

At the turning point of each case, a stranger named Harley Quin appears, asks a few simple questions, and then slips away. Old tragedies, hidden motives, and half-forgotten clues rise to the surface in country houses, winter parties, and seaside resorts.

Part mystery, part uncanny tale, these stories show Christie in a more dreamlike, experimental mood. Some mysteries end in justice; others end in uneasy truth.
