“The critical scene of the mystery is when the detective enters. The action shifts to Sherlock’s sitting room. The little Belgian man with the waxed moustache appears in the lobby of the grand hotel. The gentle old woman with a bag of knitting comes to visit her niece when the poison pen letters start going around the village. The private detective comes back to the office after a night of drinking and finds the woman with the cigarette and the veiled hat this is when things will change.”
