Dr. Craven did not look happy when he left the room.  He gave a puzzled glance at the little girl sitting on the large stool.  She had become a stiff, silent child again as soon as he entered and he could not see what the attraction was.  The boy actually did look brighter, however—­and he sighed rather heavily as he went down the corridor.

“They are always wanting me to eat things when I don’t want to,” said Colin, as the nurse brought in the tea and put it on the table by the sofa.  “Now, if you’ll eat I will.  Those muffins look so nice and hot.  Tell me about Rajahs.”

CHAPTER XV

NEST BUILDING

After another week of rain the high arch of blue sky appeared again and the sun which poured down was quite hot.  Though there had been no chance to see either the secret garden or Dickon, Mistress Mary had enjoyed herself very much.  The week had not seemed long.  She had spent hours of every day with Colin in his room, talking about Rajahs or gardens or Dickon and the cottage on the moor.  They had looked at the splendid books and pictures and sometimes Mary had read things to Colin, and sometimes he had read a little to her.  When he was amused and interested she thought he scarcely looked like an invalid at all, except that his face was so colorless and he was always on the sofa.

“You are a sly young one to listen and get out of your bed to go following things up like you did that night,” Mrs. Medlock said once.  “But there’s no saying it’s not been a sort of blessing to the lot of us.  He’s not had a tantrum or a whining fit since you made friends.  The nurse was just going to give up the case because she was so sick of him, but she says she doesn’t mind staying now you’ve gone on duty with her,” laughing a little.

In her talks with Colin, Mary had tried to be very cautious about the secret garden.  There were certain things she wanted to find out from him, but she felt that she must find them out without asking him direct questions.  In the first place, as she began to like to be with him, she wanted to discover whether he was the kind of boy you could tell a secret to.  He was not in the least like Dickon, but he was evidently so pleased with the idea of a garden no one knew anything about that she thought perhaps he could be trusted.  But she had not known him long enough to be sure.  The second thing she wanted to find out was this:  If he could be trusted—­if he really could—­wouldn’t it be possible to take him to the garden without having any one find it out?  The grand doctor had said that he must have fresh air and Colin had said that he would not mind fresh air in a secret garden.  Perhaps if he had a great deal of fresh air and knew Dickon and the robin and saw things growing he might not think so much about dying.  Mary had seen herself in the glass sometimes lately when she had realized that she looked quite a different creature from the child she had seen when she arrived from India.  This child looked nicer.  Even Martha had seen a change in her.
