Mary's second adventure as an undercover agent forces her to relive some harrowing childhood experiences as she seeks the identity of a murderer.

Mary Quinn is back, now a trusted member of the Agency, the all-female detective unit operating out of Miss Scrimshaw's Academy for Girls. Her new assignment sends her into the grimy underbelly of Victorian London dressed as a poor boy, evoking her own childhood memories of fear, hunger, and constant want. As she insinuates herself into the confidence of several persons of interest, she encounters others in desperate situations and struggles to make a difference without exposing--or losing--her identity. Mary's adventure, which takes place on the building site of the clock tower of the Houses of Parliament, offers a fictional window into a fascinating historical time and place.
