A dead employer's legacy of five thousand pounds has allowed spinster Hannah Pym to resign from housekeeping and enjoy traveling the English countryside by coach. But adventure soon finds Miss Pym in the form of runaway brides, spirited heiresses, and international refugees, who continue to test her expert matchmaking skills.

The shy Miss Yvonne Grenier, a beautiful fugitive of the French Revolution, is quite terrified when a dangerous enemy boards her coach to York. Luckily, Miss Hannah Pym is also on board. Ever the matchmaker, Miss Pym sees the answer to Yvonne's plight in the hands and heart of another passenger—the Marquis of Ware.

Handsome and tailored to perfection, the Marquis has birth and fortune enough to defend Yvonne. Although the girl is of the French bourgeoisie and below his rank, Miss Pym is certain that Yvonne's Gallic graces and quick wit have more than piqued his interest. After all, a maiden in distress is irresistible—even to a confirmed bachelor.
