Quintus Fogerty was as unlike the typical detective as one could imagine. Small in size, slight and boyish, his years could not readily be determined by the ordinary observer. His face was deeply furrowed and lined, yet a few paces away it seemed the face of a boy of eighteen. His cold gray eyes were persistently staring but conveyed no inkling of his thoughts. His brick-red hair was as unkempt as if it had never known a comb, yet the attire of the great detective was as fastidiously neat as if he had dressed for an important social function. Taken altogether there was something mistrustful and uncanny about Fogerty's looks, and his habit of eternally puffing cigarettes rendered his companionship unpleasant. Yet of the man's professional ability there was no doubt; Mr. Merrick and Arthur Weldon had had occasion to employ him before, with results that justified their faith in him.
