From publisher blurb:
The most prestigious, modern way to travel: the airship Hindenburg! Only two days from the Untied States to Frankfurt in the company of the rich and famous. It's a shame one of these passengers is a killer...
Murder on the Hindenburg is an adventure scenario in the style of the closed-room murder mysteries of the 1930s. When steel magnate Stefan von Eckhardt dies under suspicious circumstances, it is up to the characters to find the killer before the airship lands in Frankfurt.
This adventure module is designed to be used with the Ubiquity system that powers Hollow Earth Expedition. There are four pre-generated characters, but you could easily use your own, and the adventure was designed to be run in a two to three hour session.
