CHAPTER IV
The difficulty was not only that Gerald had got the ring on and couldn't get it off, and was therefore invisible, but that Mabel, who had been invisible and therefore possible to be smuggled into the house, was now plain to be seen and impossible for smuggling purposes.
The children would have not only to account for the apparent absence of one of themselves, but for the obvious presence of a perfect stranger.
"I can't go back to aunt. I can't and I won't," said Mabel firmly, "not if I was visible twenty times over."
"She'd smell a rat if you did," Gerald owned—"about the motor-car, I mean, and the adopting lady. And what we're to say to Mademoiselle about you!" He tugged at the ring.
"Suppose you told the truth," said Mabel meaningly.
"She wouldn't believe it," said Cathy; "or, if she did, she'd go stark, staring, raving mad."
"No," said Gerald's voice, "we daren't tell her. But she's really rather decent. Let's ask her to let you stay the night because it's too late for you to get home."
