Reisen: Passagen in den Tod (2013)

from the back of the book:

In the footsteps of the mythos, the characters often hunt around the globe, rushing from one city to another, from one continent to another.
Travel makes this an essential element in the lives of the characters: the constant back and forth to always be where the Cthulhu Mythos rears its ugly head. The book illuminates the 20es and is divided into a source part and six adventures. Here, the characters drive with an automobile through New England, use a hellish train, get caught in a storm on a luxuray liner amidst the Atlantic Ocean, nearly get driven mad on a rundown ship off Indonesia, must save a flying boat on a transatlantic flight from a crash, and free an airship from a ghastly evil.
