A few days passed away, and Catherine, though not allowing herself to suspect her friend, could not help watching her closely. The result of her observations was not agreeable. Isabella seemed an altered creature. When she saw her, indeed, surrounded only by their immediate friends in Edgar’s Buildings or Pulteney Street, her change of manners was so trifling that, had it gone no farther, it might have passed unnoticed. A something of languid indifference, or of that boasted absence of mind which Catherine had never heard of before, would occasionally come across her; but had nothing worse appeared, that might only have spread a new grace and inspired a warmer interest. But when Catherine saw her in public, admitting Captain Tilney’s attentions as readily as they were offered, and allowing him almost an equal share with James in her notice and smiles, the alteration became too positive to be passed over. What could be meant by such unsteady conduct, what her friend could be at, was beyond her comprehension.
