Joey could not say that Noreen, Syb, and Barbara had been horrid to her; she turned red and hesitated. The Professor glanced quickly at Miss Conyngham.
"For what reason, Jocelyn?"
"Oh, just I wanted to. Of course, I didn't know it was going to rain on my quilt."
"Never mind the quilt. How often have you done it since?"
"Never, Miss Conyngham."
The Professor's black eyebrows lifted just a shade. Joey saw them and felt angry. Didn't he believe her?
"You are quite sure of that, Jocelyn?"
"Yes—honour."
"Last night," Miss Conyngham said slowly, her eyes on Joey's face, "the Professor saw a girl, a tall, slim girl in a short frock, climb in at the window of the Laboratory sometime after you were all supposed to be in bed, but before the servants had locked up. He was not near enough to be quite sure about her—but this morning he found this handkerchief under the window."
