The elder girl looked up; her voice was rather dry when she answered:
"No, I did not think that."
Christine threw her hat aside.
"I can't drive a bit," she said petulantly. "I'm so silly! I nearly ran into the wall at the gate."
"Did you?"
"Yes. Gladys, we're going over to Heston at two o'clock with Mr.
Kettering."
Gladys looked up.
"We! Who do you mean by 'we'?"
"You and I, of course."
"Oh"—there was a momentary silence, then: "There's a letter for you on the table," said Gladys.
Christine turned slowly, a little flush of colour rushing to her cheeks. She glanced apprehensively at the envelope lying face upwards, then she drew a quick breath, almost of relief it seemed.
