they're enjoyin' theirselves for sure," she said.
She was quite right, the comfortable wonderful mother creature—and she had never been more so than when she said their "play actin'" would be their joy. Colin and Mary found it one of their most thrilling sources of entertainment. The idea of protecting themselves from suspicion had been unconsciously suggested to them first by the puzzled nurse and then by Dr. Craven himself.
"Your appetite is improving very much, Master Colin," the nurse had said one day. "You used to eat nothing, and so many things disagreed with you."
"Nothing disagrees with me now," replied Colin, and then seeing the nurse looking at him curiously he suddenly remembered that perhaps he ought not to appear too well just yet. "At least things don't so often disagree with me. It's the fresh air."
"Perhaps it is," said the nurse, still looking at him with a mystified expression. "But I must talk to Dr. Craven about it."
"How she stared at you!" said Mary when she went away. "As if she thought there must be something to find out."
"I won't have her finding out things," said Colin. "No one must begin to find out yet."
