The Mystery of Drear House by Virginia Hamilton, 1987.

This book is the continuation of The House of Dies Drear, and the final book in the short series.

The Smalls are now settled into the house that formerly belonged to the abolitionist Dies Drear, who used secret tunnels to help smuggle escaping slaves to freedom as part of the Underground Railroad. Thomas Small’s father is a college professor, who finds the history of the house endlessly fascinating, especially now that they know about the hidden treasure that the caretaker, Mr. Pluto has been guarding for many years.

Apart from the Small family and Mr. Pluto, Pesty is only other person who knows where the hidden treasure is. Pesty (a nickname, her real name is Sarah) is the adopted daughter of the Darrow family, who live nearby. The Darrows are generally known to be nasty and scheming, and they have spent years looking for the treasure they know that Dies Drear hid. In the last book, Pesty helped the others to frighten off the Darrows when they were getting too close to the secret, but Thomas is still concerned that they might be a threat. He also privately questions Pesty’s loyalty, wondering if she’ll continue to keep the secret from the Darrows, although Mr. Pluto is confident that she will because she knew the secret of the treasure even before the Smalls did.

Mac, a boy about Thomas’s age, is the youngest of the Darrow brothers, and he’s not as mean as the rest of his family. Thomas kind of wants to be friends with him, but he’s not sure if he can really trust him. Mac tells Thomas that he can come over to visit sometime and that his mother is an invalid who sometimes spends months in bed. When Mac shows an interest in Thomas’s great-grandmother, who is coming to live with them, Thomas gets the idea to bring his great-grandmother over to the Darrow house to visit Mac and Pesty’s mother.

However, before they can visit Mrs. Darrow, she comes to visit them, entering their house through one of the secret passages that Thomas and his family haven’t learned about yet. She startles Thomas’s great-grandmother with her sudden arrival, and Thomas is irritated that Pesty didn’t tell him about that secret passage even though she knew about it. Pesty explains to them that her mother is mentally ill, a chronic condition of some kind, and she gets a little odd during times when she doesn’t take her medicine. Thomas’s great-grandmother seems to understand the situation, and she insists on escorting Mrs. Darrow home.

In the secret tunnel Mrs. Darrow used to come to their house, there are hidden rooms, and when they all arrive at the Darrow house, Mrs. Darrow begins telling them a kind of odd story, really little bits and pieces of stories that she has told Pesty and Mac before. Pesty seems to have a better understanding of what Mrs. Darrow is talking about than Mac does, but Thomas can tell that Mac has heard his mother tell these stories before and that he is also trying to get a better understanding of them. For some reason, Pesty seems to be holding back information from Mac as well as Thomas.

The story that seems to concern Mrs. Darrow the most is about an Indian Maiden (Native American). She seems to get upset at first when Thomas mentions that Mac had mentioned an Indian Maiden before. It turns out that the Darrows are part Native American, and the “Indian Maiden” is one of their relatives from the past. She played a role in the Underground Railroad with Dies Drear but lost her life when she was caught. The Indian Maiden was hiding secrets that Pesty is still trying to protect, and she has also been worried about Mrs. Darrow, who sometimes acts out part of the old story as if she were the Indian Maiden herself.

Meanwhile, it seems like someone is playing the ghost of Dies Drear and trying to frighten Mr. Pluto into telling him about the hidden treasure. Thomas and Pesty see the tracks of this person one day when they go to visit Mr. Pluto. The relationships between the different members of the Darrow family are complicated, and not all of them are really after the same thing.

My Reaction and Spoilers

Mrs. Darrow’s mental illness and the different motives of the younger Darrows vs. the older Darrow boys and their father are at the heart of much of the mystery and peculiarity of the Darrow family. Mac actually opposed his father and brothers the last time they tried to get the hidden Drear treasure, and since then, they’ve been shunning him. Pesty tries to look after Mrs. Darrow as best she can, but she’s been handling the job largely by herself, and at the same time, she could really use the support of a mother who can look after her. Pesty doesn’t really like all of the secrets that she has been forced to keep, but for a long time, she hasn’t felt safe in confiding the full truth of anything to anybody. She feels even more left out of the Darrow family than Mac is because she’s their adopted child, not a blood relative, even though she is always looking after Mrs. Darrow and thinks of her as her “Mama.”

The solution to many of the problems with the Darrows comes with the public exposure of the Drear treasure and the end to all the secrecy. The Smalls decide to give Mrs. Darrow the credit for finding the treasure, so although Mr. Darrow is angry that he will never get his hands on the hidden treasure that he and his family have searched for so long, they will get part of the reward money for finding it. The foundation that receives the treasure also gives jobs to Mr. Small and Mr. Darrow, changing the lives of the Darrows for the better. Even though Mr. Darrow didn’t get what his family originally wanted, they end up with something that improves their situation, and they no longer feel the need to hide Mrs. Darrow’s condition from everyone. The Darrows are freed from part of their past, and now, they’ll be able to go forward with their lives. Mr. Darrow also shows that he really cares about his adopted daughter.

The Darrows are a mixed race family, and their heritage is in keeping with real events in American history. People with mixed black and Native American heritage are sometimes colloquially known as “Black Indians,” and people with that type of mixed ancestry have existed in the Americas since Colonial times. By the end of the story, the Darrows’ full history isn’t completely explained in detail, but it seems that it was probably Dies Drear’s work with the Underground Railroad that brought their ancestors together. Freed and escaped slaves did sometimes intermarry with Native Americans.
