"This is an early Traven story, taken, in an uncredited translation, (probably by Traven himself - I have Anglicised the spelling) from The Night Visitor and other stories, Allison & Busby, 1983 - a volume long out of print. The original German version - Der Grossindustrielle - was first published by the Buchergilde Gutenburg in 1928, as part of the collection Der Busch."
