JACHIN FELL pushed aside the glass curtains between the voluminous over-draperies in the windows of the Chess and Checkers Club, and gazed out upon the riotous streets of New Orleans. Half an hour he had been waiting here in the lounge room for Dr. Cyril Ansley, a middle-aged bachelor who had practised in Opelousas for twenty years, and who had come to the city for the Mardi Gras festivities. Another man might have seemed irritated by the wait, but Jachin Fell was quite unruffled.
