A room with no number. A warning in red. A mystery hidden in the records.

Download the case for free and begin a new Faith Detectives™ adventure as Sofia, Leo, and Gabe return to Vatican City with Sister Agnes—and discover that sometimes the most important clue is what’s missing.

When an anonymous envelope arrives bearing two crossed keys, the detectives uncover a puzzling contradiction: an old inventory says a room was emptied, but another entry lists something still inside. One historical floor plan shows a doorway. Another shows only a wall.

How does a door disappear—and who wants the detectives to stop asking questions?

With archive historian Dr. Lucia Bellini guiding their investigation, the team follows a trail of eight-pointed stars, mysterious numbers, handwritten corrections, and a missing manuscript page. Then a warning written in red turns an intriguing puzzle into a case someone clearly wants left unsolved. Faith_Detectives_Case_004_The_L…

The Locked Room of the Popes is the first free downloadable e-book adventure in The Vatican Archive Mystery trilogy—and Case #004 in the growing Faith Detectives™ series.

Along the way, they’ll discover why protecting history matters—and why seeking the truth takes observation, patience, honesty, and courage.

Perfect for individual readers, families, homeschoolers, classrooms, and parish programs, this illustrated adventure includes a detective challenge, discussion questions, and a family prayer to keep the discovery going beyond the story.

The investigation begins here—and continues in Book Two: The Missing Papal Letter and Book Three: The Seal of the Fisherman.
