Helen Boyko is a woman with grown but not yet married grandchildren, living in an apartment in a building run by an elected board of the residents. She has an elderly cockapoo named Duffy. This is not the the dog that gets dognapped. Her neighbors include the president of the board, Gloria Vaunn, who has a large, friendly, completely untrained St. Bernard mix named Gunther; cranky old man Harold Keen, who has no pets and no friends; and Helen's best friend, Rita Hawthorne. There are other residents, but these are the ones we meet. Gloria Vaunn has a housekeeper named Lynn, and a son, Stewart, who is apparently financially successful, but we don't know what exactly he does.
Very near the apartment building is a café, owned and run by Carol Wildman.
Late one evening, while Gloria is out, Gunther is stolen. She comes home from a fundraising event to find her apartment door closed and locked, a glass table near the entrance knocked over and broken, and Gunther missing.
