Description: Also on the Bonnie Scots Tour are Qwill's current woman friend, Polly Duncan, the Moose County librarian; and his recently returned former girlfriend, Dr. Melinda Goodwinter, who proposes marriage. Tour leader Irma Hasselrich (a friend of Polly's and a patient of Melinda's) dies of apparently natural causes; then a jewel case and the tour-bus driver disappear. Qwill, Polly and Melinda decamp the tour early; back in Pickax City, listening to tape recordings he made along the way-and to Koko's intuitive yowls-Qwill begins to suspect that Irma was murdered. Convincing others, however, takes time and an investigation.
