The girls were passing close to the high wall which separated the Castle grounds from the warren, and as it seemed more than probable that Ronnie was inside, playing in the garden, they managed with considerable effort, and the aid of some strong ivy, to climb to the top and peep over. Here a most unexpected sight met their gaze.
On the grass, under a tamarisk bush, sat Gerda with Ronnie on her knee. She had evidently made friends with the little fellow to a great extent, for he seemed very much at home with her, and the two were laughing and joking together in the most intimate fashion. It was such an absolutely new aspect of Gerda that Deirdre and Dulcie were dumb with amazement. When, at the Dower House, had she laughed so gaily, or talked in so animated and sprightly a fashion? No shy, reserved, taciturn recluse this; her eyes were shining, and her whole face was full of a bright expression, such as the others had never seen there before.
"Hallo, Gerda! What are you doing here?" called Deirdre, finding speech at last.
Gerda dropped Ronnie, and sprang to her feet with a sharp exclamation. No one could have looked more utterly and egregiously caught. She stood staring at the two faces on the top of the wall, and offered no explanation whatever. Ronnie, however, waved his hand merrily.
"We've been playing Zoo," he volunteered. "Gerda's been a lion, and gobbled me up, and she's been an elephant and given me rides, and we were both polar bears, and growled at each other. Listen how I can growl now—Ur-ur-ugh! Oh, and look what she's given me for my birthday! It comes from Germany," producing from his pocket a little compass. "Now if ever I get lost, I can always find my way home. See, I can show you which is north, and south, and east, and west."
"You'd better be going back, Gerda," remarked Dulcie grimly. "You know we're not allowed in the Castle grounds without a special invitation."
"I'll come through the side gate," replied Gerda, turning from Ronnie without even a good-bye. Deirdre and Dulcie dropped from the wall, and met their room-mate at the identical moment when she passed through the turnstile.
"Well, of all mean people you're the meanest!" observed Deirdre. "I call it sneaky to take such an advantage, and go to play with Ronnie by yourself. We'd do it if it were allowed, but it isn't."
"I wonder his governess wasn't with him," said Dulcie. "He's generally so very much looked after."
"And as for going inside the Castle garden, it was most fearful cheek," continued Deirdre. "We, who know Mrs. Trevellyan quite well, never think of doing such a thing."
