That was necessary, since in her note Madge had stated that she would be at the studio at three unless she heard to the contrary. Therefore there was no object to be gained in merely sequestrating the note, since Madge proposed to go there unless stopped. For Lady Ellington knew well that no plan, however well-founded, could be quite certain of success; uncertainty, the possibly adverse action of Fate might work against it, and thus to let this note go--of which she had mastered the contents--was to provoke an accident the less, since, on her present scheme, she had not stopped it. For the fewer dubious things one does on the whole, the less is the risk. It is the unfortunate accident of guilt which in nine cases out of ten hangs a man. So though she had been guilty--in a way--when she wrote to Evelyn, implying Madge's acquiescence in her letter, she had the more excellent reason now, especially since she had completely mastered the contents of this note, in not taking the more questionable step of stopping it. For she knew for certain, and at the moment did not require to know more, the immediate movements of the enemy; if Madge heard nothing, she would go to the studio to-morrow at three. But no one under any circumstances could prevent her mother making her appearance there too. Again, it is true, some sort of reply might come. But the fact of a reply coming was equivalent to Evelyn's saying that he could not be there at three to-morrow, which rightly she put down as being a negligible contingency. And in this case again, if Lady Ellington could not keep watch over Madge's movements during the next ten days she felt she would be really ashamed of herself. And as she had never been that yet, she saw no reason why she should begin now. She was probably right--the chances were immensely at this moment in favour of her not beginning to be ashamed of herself. For the beginnings of shame are searchings of the heart; Lady Ellington never searched her heart, she only did her best. The evening passed in perfect harmony; and though she had a good deal to think about, she could yet spare time to be characteristically critical about the play. That was easy, since it was a very bad one, and the deeper consolations of her brain were devoted all the time to certain contingencies. This note had been posted by half-past seven; it would be received that night. Supposing there was a reply to it, it was almost certain that the answer would come at the second morning post, the one that rapped towards the end of breakfast time. If so, and if that reply was received by Madge, she had merely, in the most natural manner possible, to suggest complete occupations for the day, challenging and inquiring into any other engagement. But she did not seriously expect this--no reply was the almost certain rejoinder. In this case, Lady Ellington would be quite unoccupied after lunch.
