What this book is about
Carolyn Wells's mystery novel (one of her Pennington Wise detective series) follows an investigation where the evidence forms a damning pattern against a suspect who maintains innocence. Wells was one of the most prolific mystery writers of the early 20th century, and her work is characteristic of the era's puzzle-plot detective fiction.
