Series background & context
This series opens in the fall of 1918, with World War I still shaping daily life, and it makes smart use of that moment. The central character is Delia Markham, a former Yeoman (F) in the U.S. Naval Reserve who has been forced into a new chapter after the abrupt end of her military work. She takes a job as a typewriting teacher at the Glennon Normal School, a teachers' training school, and expects a quieter life than the one she left behind.
She does not get it.
From Mystery at Glennon Hall onward, Delia finds herself pulled into crimes that grow out of school life, local family history, and the wider unease of wartime America. She lives with her cousin Hazel, the head chef at the school, which gives the series a warm domestic center. Around them are students, staff, the Glennon family, and a town where private worries and public events constantly overlap.
That setting is one of the best things about the series. A normal school is not the most common mystery backdrop, which helps the books stand apart. Delia teaches future teachers, so the campus has rules, routines, and a steady flow of young people trying to build lives for themselves. At the same time, the Glennon family and their household bring in another layer of tension, wealth, expectations, and old secrets that do not stay buried for long.
Wallace also makes good use of Delia's background. Her naval service is not just an interesting detail. It shapes how she thinks, how she observes people, and why she is able to step into difficult situations without immediately backing away. She is practical, curious, and not easily impressed by authority. That works well in a series where so many people are managing appearances.
There is a lot of appearance-management here.
As the books continue, the cast around Delia deepens. Wesley Glennon becomes an especially important figure, and other recurring characters help turn the series into more than a string of isolated mysteries. There are shootings, betrayals, complicated loyalties, and ongoing questions that stretch from one book to the next. Even when Delia is dealing with a specific crime, the larger Glennon story keeps moving underneath it.
The tone is still accessible and inviting. These are historical cozies, not grim war novels, but the period matters. The final months of the war, changing roles for women, and the pressure on families and institutions all give the books extra texture. If you like campus mysteries, community-centered historical fiction, and a heroine who knows how to keep asking questions when everyone else grows uncomfortable, the Glennon series has a lot to offer.
