Ahoy there mateys! This be one of those books where the blurb is extremely misleading and led to some dissatisfaction.  It describes the book as "Stranger Things meets the Golden Age of Detective fiction in a rollicking supernatural detective thriller that introduces Artie Quick, a sales assistant at Filene’s in Boston, who moonlights as a amateur detective."  I did really like Artie Quick, however, she never really feels like a detective of any kind.  She signs up for a criminal investigative class that she does not complete. She hears a scream in the park that she wonders about.  Artie half-heartedly seems to want to investigate to make herself feel useful.  The majority of the book felt like a description of Artie's friendship with Theodore, which I liked.  Maybe the three parts were the problem.  Part one is ‘The Evening Institute for Young Men’  which details the class and friendship.  Part two is ‘The Boston School of Magic’ which discusses Theodore's magic studies and his professor's life.  Part three ‘The Excavated Prison’ is where the mystery is explained and dealt with.  I personally felt that the first two parts were great and the third part felt like a completely different book.  Lots of folks loved this.  Wish I would have. Arrrr!
