Following her childhood rescue from the gutters of Calcutta, Mary Grace's life has been an astonishing rags-to-riches tale. The Wellings raised the half-Indian orphan with all the love and care the childless couple possessed, allowing her to grow into a beautiful and refined woman. But upon Mr. Welling's death, it is time for Mrs. Welling to take Mary home to England—home to Meriden Park.
Despite her genial nature, Mary is received with suspicion by the villagers. For his part, however, Mr. Robert Markham is intrigued by the curious new beauty in town. Determined to make her acquaintance, he offers Mary a bargain she can't refuse: a hot cross bun for a kiss. That seemingly innocent exchange is the first of many encounters between Robert and Mary, whose friendship blossoms into love during long walks in the privacy of Sherwood Forest. But the shadows of the forest hide a sinister secret, one Mary fears Robert might be a part of. As the mystery of the recent string of murders creeps closer and closer, Robert and Mary are drawn into a dangerous game, and unless she can unearth the truth, the couple risks losing one another forever.
