When Susan first arrives, as she steps from the boat she has a cape on but the cape is gone when she enters the house and neither she nor anyone else is carrying it.
When Irene sends the men out of the room before Barrie comes in, she takes a cigarette from a porcelain box on the table, tapping it on the box lid. Cut to Barrie opening his car door and stumbling up the steps to the porch. There is an immediate cut back to Irene who is just putting the lid back on the box.
