Threadbare by Monica Ferris is the fifteenth book in the Needlecraft Mystery series. Two homeless women are discovered frozen to death and one of them was carrying a scrap of Hardanger embroidery. Betsy is once again roped into discovering what links the two women together beyond their homelessness.
For fans of the series who love the book for the inclusion her needlecraft store, this one is a departure. Betsy does a lot of traveling by train and an abortive attempt to travel by airplane.
There's also a lot of time spent on Godwin learning how to play golf. Which I guess, if you're a fan of either golf or Godwin, you'll be interested. If you're not, then these scenes might get in the way of the mystery for you.
Despite the numerous departures from form, I found myself drawn right into the mystery. Somehow the series always seems strongest when set in the winter time. Ferris is really good at describing the weather conditions and since it's something I don't experience here in the Bay Area it adds some extra excitement to the plot.
