The Mystery of the Black Raven

Back in the days of the gold fever, one of the Aldens' ancestors was part of the Four Rock Miners, a group that met annually in Skagway, Alaska. Now the Aldens are keeping the tradition alive by attending a reunion with the descendants of the other miners. But when the raven statue and scrapbook that have belonged to the group for more than a century go missing, it looks like the Aldens have stumbled onto another case!
