This collector's edition comprises the first five episodes of the popular Baumgartner & Momsen crime and mystery series for intermediate and advanced German learners: Mord am Morgen, Die Dritte Hand, Des Spielers Tod, Zum Bärenhaus and Heidis Frühstück.

Harald Baumgartner is a grumpy old-fashioned flatfoot with an infallible instinct for catching killers, Katharina Momsen is a sassy sleuth and a cold sober markswoman. Together they are "Baumgartner & Momsen", the quirky but effective team feared by crooks and criminals everywhere.

Each story invites readers to help solve a crime and pick up important German vocabulary along the way. At the end of every chapter relevant words are translated into English, followed by short text-comprehension questions. (The correct answers can be found at the end of each story in the Answer Key section.) Free Flashcards are provided in ANKI format and via Quizlet links.)

While the stories themselves are primarily aimed at creating an immersive and entertaining reading experience for German learners, the language is specially designed to familiarize readers with unique forms of spoken German with a special emphasis on dialogue and common idiomatic phrases.
