Maria knew Donna Teresa’s story well, for her friend Giuliana Parenzo had told it to her; and as Maria was in no way called upon to make a public denial of it, she simply said nothing and was grateful to the gossip for treating her so kindly. Giuliana was not curious, and if she rightly guessed some part of the secret which her friend had never told her, she would not for worlds have asked her a question.

The three new-comers were all in the best possible humour, and the ladies wore perfectly new spring frocks of the very becoming model that was in fashion that spring; the one was of the palest grey and the other of the softest dove-colour. Giuliana was a dark woman with a quiet face; Teresa Crescenzi was very fair, fairer, perhaps, than all probability, and when she was excited she screamed.

‘Dear Maria!’ she cried in a high key, after the first words of greeting. ‘You are quite adorable in that costume! The Princess Campodonico was saying just now that it is a real pleasure to see you in colours at last. Maria has worn nothing but black and grey for seven years,’ added the lively lady, turning to Castiglione.

‘We all are dying of thirst,’ said Giuliana, seeing the look of annoyance in her friend’s face. ‘We all want lemonade, and we all want it at once. Won’t you let me come inside and help you?’

‘No, dear,’ answered Maria with a grateful look. ‘I really do not need help, and you do not look at all like a Neapolitan Acquaiola in that frock! Besides, Oderisio Boccapaduli is supposed to be my adjutant, but he has gone off to smoke a cigarette.’

She was very busy, and Donna Teresa turned to Castiglione.

‘And where in the world have you been since I met you in Florence last year?’ she asked. ‘I thought your regiment was coming to Rome at the beginning of the winter. I am sure you told me so.’

‘You are quite right. My old regiment came to Rome before Christmas, but I had already exchanged into another.’

In spite of herself Maria glanced at Castiglione as he spoke, but he was not looking at her, nor even at Donna Teresa. From the place where the booth was situated he could see a certain clump of ilex-trees that grow near what has always been called the Piazza di Siena, I know not why. Maria saw that his eyes were fixed on that point, and she shivered a little, as if she felt cold.

‘Why did you exchange?’ Donna Teresa asked, with the shameless directness of a thoroughly inquisitive woman. ‘Did you quarrel with your colonel, or fight a duel with a brother officer?’
