By Adele Whitby, Author. Discover the chilling secrets surrounding Maggie O’Brien’s disappearance from Chatswood Manor in the third book of an irresistibly entertaining historical fiction mystery series. Elizabeth and Katherine Chatswood are on the verge of turning twelve years old, which means that the grandest birthday ball in all of England is just a few weeks away! Chatswood Manor is bustling with activity, but in the midst of all the excitement, an Irish refugee named Sean O’Brien shows up in search of his long lost wife Maggie, who was employed at Chatswood Manor many years ago. Mr. O’Brien is turned away by Chatswood’s stern butler, but not before Elizabeth and Katherine hear his story. Through Mr. O’Brien they also find out about the potato famine in Ireland, and are shocked and saddened to hear that so many people are suffering in a place that’s not that far away. The twins vow to not only help Mr. O’Brien find Maggie, but also to somehow help the people of Ireland. But how are two young girls in a manor home in England going to help starving people in Ireland? After their papa tells them it’s not their problem to worry about fixing, they have no choice but to come up with a very ambitious—and very top secret—plan. Meanwhile, as they investigate Maggie’s disappearance, they uncover some startling clues, which lead them to discover even deeper mysteries hidden within Chatswood Manor. For ages 7 and up.
