Solving Mr Roger's Murder (10)

He was sulking, she could tell. Scarlet didn't know how to make it up to him and watched as he dusted for fingerprints after they found a red-tagged compact powder case that belonged to Miss Roger. He met up with her in the room with an unhappy face and didn't return Scarlet's greeting with enthusiasm. That fingerprint easily matched with the wine glass in the kitchen and the one from the safe to nobody's surprise.

The writer didn't know what to say to her sulking boyfriend. She could guess why he wasn't happy but there really wasn't a need for him to worry. She made it through safely, didn't she? Still, the writer searched Miss Roger's room slowly, thinking of a way to cheer him up.
