Mr. John Quincy Harrington is the American businessman with whom Ashenden travels to Petrograd, Russia. During the 11 day train trip Ashenden learns all that he believes there is to know about Harrington. Harrington considers himself a top rate speaker and story teller. Ashenden, however, does not enjoy Harrington's slow monotone and is frustrated by his traveling companion's inability to be quiet. Harrington even prefers to read aloud, a habit that Ashenden finds very distasteful. During the span of the trip, Harrington tells Ashenden about his wife, his children, his business, and his education. Ashenden feels there is nothing left for him to learn about Harrington. Despite his incessant talking, Harrington does have the endearing quality of taking good care of Ashenden while he is sick during the train trip.
