Two homeless women are found frozen to death in Excelsior, Minnesota, and the only link between them is that they each had a relative who patronizes Betsy Devonshire's needlecraft shop. Officer Mike Molloy suspects poison, and suspects the relatives. One comes to Betsy, who has solved more than one murder, and asks her to take the case on. It becomes far more complex than Betsy had envisioned, as she learns the plights of the homeless and the shelters that take them in, but she won't stop until she solves the crime.
There were things about this book that I both liked and didn't like. It's well written, with good characters and setting, the details on needlework were interesting, and clearly the author did her homework about homeless issues. What didn't work so well was the awkward infodumps about homelessness issues, and the vast plethora of detail that had nothing to do with the plot. Usually in a murder mystery, detail is there to build the setting or further the plot. Here, I couldn't figure out the purpose of detailing an indoor golfing outing by two characters uninvolved in the main plot, or the Rainman-level detail about taking the train to Fargo (seriously, it could be an instruction manual), or many other things. I love detail, but not if it serves no purpose. Also, I think there was a big plot gaffe, though I could be wrong. A woman comes to the funeral of one of the dead women, gives a eulogy and later tells Betsy about her, but then doesn't recognize her picture. Betsy doesn't comment about that and it doesn't come into the plot at all. Maybe I missed something, but it seemed odd, at least. So, overall, average mystery with no twist--the murderer was one of the few suspects Betsy identified, for clear and obvious reasons.
