From the Introduction:
Free Introductory Adventure
New York, October 1932. Spirits walk amongst the living.
When the detectives of Arcana Agency are called to New York City's Brooklyn Museum, they cannot guess at the web of trickery and intrigue that will soon wrap itself around them.
This mini-gamebook is offered completely free of charge, in order to promote Megara Entertainment's ongoing Kickstarter project for ARCANA AGENCY: THE THIEF OF MEMORIES. The latter is to be a full-length, full-color gamebook that continues the adventures of Humphrey Brown, Joe Strelli and Tom Shanigan.
