Book excerpt: Nancy Atherton's seventeenth in the New York Times bestselling series sees the sleepy village of Finch set aflutter by a bewitching mystery from its past. Watch out for Nancy Atherton's latest, Aunt Dimity and the King's Ransom, coming in July 2018 from Viking! Last year, the otherworldly sleuth's devoted fans secured a place on the New York Times bestseller list for Nancy Atherton's Aunt Dimity and the Family Tree. Now Lori and Aunt Dimity are back on the list—and this time, they're on a witch-hunt. At first glance, the unassuming Mrs. Amelia Thistle is a disappointment to the villagers of Finch, but Lori Shepherd isn't fooled by the new arrival's bland persona. Amelia is a world-famous artist, traveling incognito, and, after unearthing a fragment of a family diary hinting that Mistress Meg, the Mad Witch of Finch, might be one of her ancestors, she's come to Finch in search of the truth.
