Charlie's visit to Paris, ostensibly a vacation, is really a mission to investigate a bond-forgery racket. But his agent, apache dancer Nardi is killed before she can tell him much. The case, complicated by a false murder accusation for banker's daughter Yvette, climaxes with a strange journey through the Paris sewers.

Mary Whitman has gone to Reno to obtain a divorce. While there she is arrested on suspicion of murdering a fellow guest at her hotel (which specializes in divorcers). There are many others at the hotel who wanted the victim out of the way. Charlie comes from his home in Honolulu to solve the murder.
