Lipstick stain?
If it can get on clothes, it must be from a very close distance.
Brought back to the apartment?
Overnight?
Otherwise, what could a single man and woman do in an apartment?
Cressida Jones slowly retracted the hand pushing the door, turned around and left. Tim Payne was completely stunned, looking incredulously at his uncle: "What are you talking about?"
"Did she set you up again?" Martin Yates frowned.
"No, I..."
"Don't look so wronged, I can't possibly wrongfully accuse you!"
"I really didn't!"
"When you were single before, you could flirt with anyone you wanted." Martin Yates scoffed, "But now, since you've chosen to be with that girl, you need to uphold moral integrity and not mess around. Otherwise, even if you are my nephew, I will have to act righteously against you."
"Break your leg!"
Tim Payne knew his uncle too well; he wouldn't accuse him without a reason. But he really couldn't recall when he got a lipstick stain on his clothes.
