Do you think Daisy knows about Tom’s “other woman”? Give an example from the text to back up your opinion.

Yes, Daisy knows about Tom's other woman.

“She might have the decency not to telephone him at dinner time. Don’t you think?” Almost before I had grasped her meaning there was the flutter of a dress and the crunch of leather boots, and Tom and Daisy were back at the table.

The telephone rang inside, startlingly, and as Daisy shook her head decisively at Tom the subject of the stables, in fact all subjects, vanished into air.

I couldn’t guess what Daisy and Tom were thinking, but I doubt if even Miss Baker, who seemed to have mastered a certain hardy scepticism, was able utterly to put this fifth guest’s shrill metallic urgency out of mind. To a certain temperament the situation might have seemed intriguing — my own instinct was to telephone immediately for the police.
