The Ebony Cross — Nick Carter

WHEN DEATH GARBLES A CODED MESSAGE, NICK CARTER DISCOVERS AN INTERNATIONAL DOUBLECROSS

It started out as a routine defection and the exit plan seemed airtight. Since scientist Hans Metzger had supposedly solved the cost factor of an alternate energy source, AXE agreed to send Nick Carter to Budapest to direct the escape of Metzger and his beautiful daughter.
