The Tree of Heaven by May Sinclair

Three more years passed and Frances had fulfilled her promise. She had taken Veronica.

The situation had become definite. Bartie had delivered his ultimatum. Either Vera must give up Major Cameron, signing a written pledge in the presence of three witnesses, Frances, Anthony and Bartie's solicitor, that she would neither see him nor write to him, nor hold any sort or manner of communication with him, direct or indirect, or he would obtain a judicial separation. It was to be clearly understood by both of them that he would not, in any circumstances, divorce her. Bartie knew that a divorce was what they wanted, what they had been playing for, and he was not going to make things easy for them; he was going to make things hard and bitter and shameful He had based his ultimatum on the calculation that Vera would not have the courage of her emotions; that even her passion would surrender when she found that it had no longer the protection of her husband's house and name. Besides Vera was expensive, and Cameron was a spendthrift on an insufficient income; he could not possibly afford her. If Bartie's suspicions were correct, the thing had been going on for the last twelve years, and if in twelve years' time they had not forced his hand that was because they had counted the cost, and decided that, as Frances had put it, the "game was not worth the scandal."
