A full-blooded romance of the eighteenth century, when the legend of the Headless Horseman and a proposed marriage de convenance both have their impact on the mystery of a golden talisman ring. The ravishing beauty, Eustacie de Vauban had been snatched from the excitement and the danger of the French Revolution to be sheltered in the dull safety of a manor house in England of Lord Lavenham, her grandfather. But, the worst of all, she was being compelled to marry her cousin Sir Tristram Shield, a boring gentleman thirteen years her senior. Neither Eustacie nor Tristram, share the slightest inclination to marry one another. Yet it is Lord Lavenham's dying wish. For there is no one else to provide for the old man's granddaughter while Ludovic Lavenham, his heir, remains a fugitive from justice, falsely accused of murder.

Eustacie's impetuous spirit rebelled, and she fled. Setting out alone in the dark forest spirited she was terrified when stumbles into a band of smugglers, but their leader is a strangely familiar young man, he is her cousin Ludovic, who is in hiding and has disguised himself as a smuggler. She is delighted to be having an adventure at last, and he is a man whose irresistible charm swept her into a maelstrom of terror, deceit -- and passionate love. Pursued by the law, Eustacie and Ludovic find refuge at an unassuming country inn. And the delightfully sensible couple who try to keep them out of trouble... The resourceful Miss Sarah Thane and the clear-thinking Sir Tristram Shield gamely endeavor to prevent Ludovic's arrest and Eustacie's ruin as the four conspire to recover the missing talisman ring that will clear Ludovic's name.
