In which novel are "Hocking", an American cotton millionaire; "Steinemann", a German coal mogul; "Von Gratz", another German millionaire, this time in steel; and "Hiram C Potts", an American shipping man, collectively invited to pay �!million to a criminal genius in return for which he guarantees to orchestrate industrial chaos in post WW1 Britain?
