This tenth, and last of the tile-pictures was on the left of the western door; but not until Antonio ceased speaking did he notice a small leather-covered box resting on the ground at the foot of the green and yellow border of azulejos. It was gilt-lettered P. L. K.-T. The lid was off, showing the stoppers of four chemists' bottles and some fine steel tools. In the same instant, both Antonio and young Crowberry had the same thought. "Lord, lay not this sin to their charge." The words were grimly appropriate to Sir Percy's act of sacrilege; yet young Crowberry felt sure that Antonio had only recognized their appropriateness when it was too late. As for the monk, although his eyes met Isabel's for no more than a moment, he saw that she was wounded. "When was the Saint hanged?" asked young Crowberry, in order to end the awkward pause. "In what reign?" "In the reign of Isabel," Antonio answered. Young Crowberry opened his eyes wide. The monk, however, had already realized his second mishap. "I mean Elizabeth, Queen Elizabeth, of course," he burst out. "The Portuguese for Elizabeth is Isabel. It's the same name." But Miss Kaye-Templeman was already moving towards the cloister doorway. Antonio, suddenly losing his English, turned desperately to young Crowberry. "You've done it this time," said the youth dolefully. "Wait here," commanded Antonio, in Portuguese. "Don't follow." He sprang after the lady and overtook her in the cloister, although she quickened her footsteps at the noise of Antonio's. When she saw that explanations were inevitable, she got in the first word. "Senhor da Rocha," she said, haughtily, "I am willing--perhaps over willing--to be talked to. But I decline to be talked at. This is your gratitude for my offer of help. As for 'the reign of Isabel,' I am too dull to see the joke; but I can see the insult." She walked on. "Hear me one moment, I entreat," cried Antonio. "Have we not, both you and I, enough troubles, solid troubles? I have told you some of mine; and, although I do not know what they are, I can see that you have great sorrows too. For Heaven's sake let us not add to them by needless misunderstandings." He kept level with her as she walked; but she heard him with averted eyes. "I swear," he added, "that I was not talking at you. I swear I didn't catch sight of your father's hateful tools till I had finished speaking. As for 'the reign of Isabel,' I am a Portuguese. In Portuguese King Charles is Carlos, King Edward is Duarte, King James is Thiago, Queen Elizabeth is Isabel. Those bottles and tools upset me; and I forgot to translate the name." When he saw that she neither vouchsafed him an answer nor paused in her walk his pride was roused.
