3From Susan Wittig Albert, the New York Times bestselling author of A Plain Vanilla Murder, comes a tightly crafted novel that juxtaposes the disappearance of a rare, remarkably illustrated 18th-century herbal with the true and all-too-human story of its gifted creator, Elizabeth Blackwell.

​Herbalist China Bayles' latest adventure takes her to the mountains of North Carolina, where her friend Dorothea Harper serves as the director and curator of the Hemlock House Library, a priceless collection of rare gardening books housed in a haunted mountainside mansion that once belonged to Sunny Carswell, a reclusive heiress. But the most valuable book--A Curious Herbal, created by Elizabeth Blackwell in the 1730s--is missing and Dorothea is under suspicion.

China's search for the thief takes on a new urgency when she discovers Miss Carswell's bookseller, the victim of an attempted murder. Is his shooting connected with the theft? And there are other urgent questions: What is the Hemlock Guild? Who owns Socrates.com? Did Sunny Carswell really kill herself, or does her ghost have a different story to tell? And what is the real truth behind the many tantalizing mysteries of A Curious Herbal?

Hemlock is a compelling mix of mystery and herb lore, past secrets and present sins, and characters who are as real as your friends and neighbors--in an absorbing novel that only Susan Wittig Albert could create.
