The Charity Shop Detective Agency

I wonder what's behind the rise in senior-citizen-focused books, particularly in the true crime genre. In the last quarter alone, I've read five books where elderly women living alone have been the main characters, and I've really enjoyed their portrayal – independent, cheerful, and happily surrounded by their older female friends. This one doesn't do anything particularly unique, but it was a pleasant, cosy read. Engaging enough for me to reach for book two. :)
