In The Curious Incident of the Dog in the Night-Time, character Christopher Boone is an eccentric and gifted young man who gains a deeper understanding of himself while solving a neighborhood mystery.

Central to the story is Christopher's discovery of a cache of old letters. Whether it’s uncovering family secrets or getting the dirt behind a historical rumor, primary sources often shed light on even the murkiest mysteries.

Find out how to explore these materials in HSP’s interactive, hands-on workshop presented in partnership with the National Archives at Philadelphia. Participants will become history detectives, looking for clues in letters, indentures, court records, and other primary sources as they solve real-life history enigmas from Philadelphia’s past.

This program is part of the Free Library of Philadelphia's citywide "One Book, One Philadelphia" initiative.
