"Living on her family's idyllic lakeside estate in Cornwall, England, Alice Edevane is a bright, inquisitive, innocent, and precociously talented sixteen-year-old who loves to write stories. One midsummer's eve, after a beautiful party drawing hundreds of guests to the estate has ended, the Edevanes discover that their youngest child, eleven-month-old Theo, has vanished without a trace. What follows is a tragedy that tears the family apart in ways they never imagined. Years later, having enjoyed a long, successful career as an author, Alice is now eighty years old and living in London. Theo's case has never been solved, though Alice still harbors a suspicion as to the culprit. Miles away, Sadie Sparrow, a young detective in the London police force, is staying at her grandfather's house in Cornwall. While out walking one day, she stumbles upon the old estate now crumbling and covered with vines, clearly abandoned long ago. Her curiosity is sparked, setting off a series of events that will bring her and Alice together and reveal shocking truths about a past long gone yet more present than ever."--Cataloger's summary of various websites.
