Eleven o'clock came, half past, and a quarter to twelve, without Mary appearing. By then he had decided that she must have gone out to dinner with a man and the thought annoyed him considerably. Although she had given him to understand that she had no family, the fact that she appeared to have no friends at all had often puzzled him. Even if she had not been living for a long time in London, it seemed strange that any young widow with her attractions should not have acquired at least one man friend. That she had not, thus leaving him a free field, he had come to accept; so, now he believed that someone had entered it against him, he felt a quite unjustified resentment.

Animated by more than a suspicion of jealousy, he decided to continue his watch, so that when his rival brought Mary home he might have a sight of him. Between midnight and one the volume of passing traffic down London's long main western artery fell steeply, the buses ceased, while private cars and taxis, from having been a steady stream, were reduced to a trickle. By half past one Barney began to think of throwing his hand in. It was an hour since he had run out of cigarettes, and Mary's failure to return suggested that she had not only gone out to dinner or a show, but also gone on to supper somewhere.

He had been telling himself that if she was out with a man it was probably some middle-aged director or important customer of one of the fashion houses for which she modelled, and that she had accepted an invitation to dine rather than give offence; but, if so, she should have been home by this time. The idea that she was more probably dancing with some young, attractive man now became insistent in his mind, and the memory of her firm young body against his own when they had danced together added fuel to his jealous imaginings.

Two o'clock came, and with it the conviction that Mary and her new beau must have gone on to a night club, which meant that she might not now be home for another couple of hours. More put out than he had been for a long time, Barney hailed a taxi that was crawling westward and had himself driven to Warwick Square.

While he undressed, he had a whisky and soda and some biscuits; then, as he got into bed, he tried to put Mary out of his mind. It was no good, but his thoughts did take another direction. Perhaps that evening she had gone out with a chap, yet it seemed strange that she had also been out the night before and out, apparently, on the several occasions when he had tried to ring her up. The explanation might be that she had suddenly decided to take a holiday.
