It's 1785 and flyers are showing up all around Boston complaining that the Hays family is holding Jewish religious services in their home.

Armed only with courage, conviction, and some amateur sleuthing skills, cousins Catherine Hays and Judah Truro set out to investigate, joined by their friend Joseph, Paul Revere's son. Can the three friends find the culprit and get him to stop?

This historical fiction transitional chapter book for ages 6-8 features real-life American heroes, focuses attention on the principle of religious freedom in the early days of the United States, and introduces young readers to Moses Michael Hays, Boston's most prominent Jewish citizen of that time.
