This novel is a mystery set in 1855 in Massachusetts and Washington DC. Willa's too timid to really investigate the murder, but Emily's bold, curious, and wants justice for Willa. Emily's used to getting her way and had a certain disbelief that anyone would harm her family. Together, they asked questions, poked around, and found clues as to why Willa's brother was murdered. It's a clue-based puzzle mystery, though I didn't think it was very difficult to figure out whodunit once they uncovered what Willa's brother had been doing. Historical details about the time and the Dickinson's lives were woven into the story and brought it alive in my imagination. The main characters were interesting and likable. There was no sex or bad language. Overall, I'd recommend this enjoyable historical mystery.
