He lifted the heavy brass knocker, and struck thrice. The sound of footsteps came from within, and he knew at once that they were Caterina's. Middle-aged, phlegmatic and solid she had loved both him and Tayoga, despite tricks and teasing, but he knew her very phlegm would keep her from being startled too much. Only an earthquake could shake the poise of Caterina. The door swung slowly open. The nature of Caterina was cautious and she never opened a door quickly. "Good-morning, Caterina," said Robert. "Is Master Jacobus in? I stayed away a bit longer than I intended, and I wish to make my apologies to him, if I've caused him any inconvenience." The mouth of Caterina, a wide cleft, opened full as slowly as the door and full as steadily, and her eyes seemed to swell at the same time. But she did not utter a word. Words might be forming in her throat, though they were not able to pass her lips. But Robert saw amazement and joy in her eyes. She knew him. That was evident. It was equally evident that she had been struck dumb, so he grasped her large and muscular hand and said: "I've come back, Caterina, a trifle late 'tis true, but as you see I'm here. It's not my fault that I've been delayed a little. I hope that Master Jacobus is well. I know he's in his study as the odor of his pipe comes floating to me, a pleasant odor too, Caterina; I've missed it." "Aye! Aye!" said Caterina. It was all she could manage to say, but suddenly she seized his hand, and fell to kissing it. "Don't do that, Caterina!" exclaimed Robert, pulling his hand away. "You're glad to see me and I'm glad to see you. I'm no ghost. I'm solid and substantial, at least ten pounds heavier than I was when I went away suddenly at the invitation of others. And now, Caterina, since you've lost your voice I'll go in and have a talk with Master Jacobus." Caterina's mouth and eyes were still opening wider and wider, but as Robert gave her an affectionate pat on the shoulder she managed to gasp: "You haf come back! you wass dead, but you wouldn't stay dead." "Yes, that's it, Caterina, I wouldn't stay dead, or rather I was lost, but I wouldn't stay lost. I'll go in now and see Master Jacobus." He walked past her toward the odor of the pipe that came from the study and library of Mr. Huysman, and Caterina stood by the door, still staring at him, her mouth opening wider and wider. No such extraordinary thing had ever happened before in the life of Caterina, and yet it was a happy marvel, one that filled her with gratitude.
