In the Diplomatic Service

Dick Stansbury chooses a life of travel and pleasure rather than a more useful career. He returns from three years of foreign travel. His uncle, Major Blaine, interests him in a bold breach of ethics made by one of the foreign diplomats, Doctor Montell, but as yet nothing has been proved against the doctor, as he knows all the men in the Secret Service in Washington. Dick met him abroad, and Major Blaine persuades him to undertake the task of Doctor Montell's unmasking. Beverly Ryerson has a friend, an eccentric young authoress, Helen Wardlow, who is disgusted because, she says, there is no more originality in life. Beverly assures her that such is not the case. Dick, Beverly, Doctor Montell, Helen, Mrs. Ryerson, Beverly's step-mother, and her nephew, Lyna Hardi, who is loaning her money to pay her bridge debts, and who in return demands that she aid his cause with Beverly, are all at the Diplomats' Ball.

Montell is determined to have the invention at once, and Hardi attempts to steal it for him, but is prevented by a Secret Service man. His reason for this move is that in trying to discredit big rival he has told Beverly that Dick is a traitor to his country. He has arranged for Beverly to overhear Dr. Montell and Dick talking about the invention. Though Dick has so far refused to sell, she fears he may succumb to the doctor's inducements, and to save him Beverly surreptitiously takes the model to her own room, though it is soon returned to Dick by one of his detectives. Montell and two accomplices then try to steal the model. Dick has been warned of their approach. He extends a wire from one of the house-lights to the model, and gets the janitor to operate a magneto at a signal. When the three malefactors step on a wet rug with the machine, they ar
