Leaving two sentries--the one just outside the breach near the wall, the other on the sandbags--the rest of the party hurried up on the roof. Shots were still being fired, and there was a confused sound of shouting; then a cavalry trumpet rang out sharply, and presently three shots fired in quick succession came upon the air. “That is the signal agreed on,” the Major said: “he is safely beyond their lines. Now it is a question of riding; some of the cavalry will be in pursuit of him before many minutes are over.” Forster’s adieus had been brief. He had busied himself up to the last moment in looking to the saddling of the two horses, and had only gone into the house and said goodby to the ladies just when it was time to start. He had said a few hopeful words as to the success of the mission, but it had evidently needed an effort for him to do so. He had no opportunity of speaking a word apart with Isobel, and he shook her hand silently when it came to her turn. “I should not have given him credit for so much feeling,” Mrs. Doolan whispered to Isobel, as he went out; “he was really sorry to leave us, and I didn’t think he was a man to be sorry for anything that didn’t affect himself. I think he had absolutely the grace to feel a little ashamed of leaving us.” “I don’t think that is fair,” Isobel said warmly, “when he is going away to fetch assistance for us.” “He is deserting us as rats desert a sinking ship,” Mrs. Doolan said positively; “and I am only surprised that he has the grace to feel a little ashamed of the action. As for caring, there is only one person in the world he cares for--himself. I was reading ‘David Copperfield’ just before we came in here, and Steerforth’s character might have been sketched from Forster. He is a man without either heart or conscience; a man who would sacrifice everything to his own pleasures; and yet even when one knows him to be what he is, one can hardly help liking him. I wonder how it is, my dear, that scamps are generally more pleasant than good men?” “I never thought about it, Mrs. Doolan,” Isobel said, roused to a smile by the earnestness with which Mrs. Doolan propounded the problem; “and can give no reason except that we are attracted by natures the reverse of our own.” Mrs. Doolan laughed. “So you think we are better than men, Isobel? I don’t--not one bit. We are cramped in our opportunities; but given equal opportunities I don’t think there would be anything to choose between us. But we mustn’t stay talking here any longer; we both go on duty in the sick ward at four o’clock.” The enemy’s batteries opened on the following morning more violently than before. More guns had been placed in position during the night, and a rain of missiles was poured upon the house. For the next six days the position of the besieged became hourly worse. Several breaches had been made in the wall, and the shots now struck the house, and the inmates passed the greater part of their time in the basement.
