Hewitt touched his companion's arm, and the two hastily but noiselessly made their way back along the passage to the study. Miss Garth left the open framing as it was, reached the top of the landing, and without stopping proceeded along the passage and turned up the main staircase, while Hewitt and Mr. Crellan still watched her from the study door.
At the top of the flight she turned to the right, and up three or four more steps toward her own room. There she stopped, and leaned thoughtfully on the handrail.
"Go up," whispered Hewitt to Mr. Crellan, "as though you were going to bed. Appear surprised to see her; ask if she isn't well, and, if you can, manage to repeat that question of mine about secret hiding-places in the house."
Mr. Crellan nodded and started quickly up the stairs. Half-way up he turned his head, and, as he went on, "Why, Nelly, my dear," he said, "what's the matter? Aren't you well?"
Mr. Crellan acted his part well, and waiting below, Hewitt heard this dialogue:
"No, uncle, I don't feel very well, but it's nothing. I think my room seems close. I can scarcely breathe."
"Oh, it isn't close to-night. You'll be catching cold, my dear. Go and have a good sleep; you mustn't worry that wise little head of yours, you know. Mr. Hewitt and I have been making quite a night of it, but I'm off to bed now."
"I hope they've made you both quite comfortable, uncle?"
"Oh, yes; capital, capital. We've been talking over business, and, no doubt, we shall put that matter all in order soon. By the bye, I suppose since you saw Mr. Hewitt you haven't happened to remember anything more to tell him?"
