The Great Gatsby, intriguing

Could you please tell me the meaning of "intriguing" in this passage from the first chapter of The Great Gatsby?

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. Among the broken fragments of the last five minutes at table I remember the candles being lit again, pointlessly, and I was conscious of wanting to look squarely at every one and yet to avoid all eyes. 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 skepticism 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.
