1. When Heidt is searching her apartment he opens up the bottle of perfume on her dressing table, rubs a bit on the lapel of his jacket and then sniffs.
2. The dainty after-dinner cups of coffee the gentlemen have their cigars at the club.
3. Whenever Alice buzzes someone into her apartment building, the doors make clicky-clicky noises.
