Surgeon's apprentice Zachary Walsh knows that his master, John Howard, prides himself on his rationality. But John cannot explain how or why Mary Toft, the wife of a local journeyman, has managed to give birth to a dead rabbit. When this singular event be­comes a regular occurrence, John and Zach­ary realize that nothing in their experience as rural physicians has prepared them to deal with a situation like this--strange, troubling, and possibly miraculous. John contacts sev­eral of London's finest surgeons, three of whom soon arrive in Godalming to observe, argue, and perhaps use the case to cultivate their own fame.

When King George I learns of Mary's plight, she and her doctors are summoned to London, where Zachary experiences a world far removed from his small-town ex­istence and is exposed to some of the dark­est corners of the human soul. All the while Mary lies in bed, as doubts begin to blossom among her caretakers and a growing group of onlookers waits with impatience for an­other birth, another miracle.
