Ulfkotte died shortly after writing Gekaufte Journalisten. Whether he was assisted on his journey will likely never be known.
The English language edition was schedule for release in 2017 (iirc). It never emerged and eventually disappeared from Amazon preorder - the original publisher appears to have been leaned on. It is finally available in paperback for $35.
Formerly entitled “Journalists for Hire,” the English edition under a new publisher now goes under the rather more racy (and honest) title: “Presstitutes Embedded in the Pay of the CIA: A Confession from the Profession”
