ten o'clock
The child tossed around and waved her arms , muttering about a geranium sea , and a little boat on it . Nurse Nannie puttered about the room for some time , picking up things , and laying out the girls ' clothes for the next day . Then she put out the lights and went away to her own room . It was , perhaps , ten o'clock when Kitty threw back the bedclothing , and slowly got out of bed . She was sound asleep , and she walked across the room with a wavering , uncertain motion , but went straight to the French window , which was still part way open . Kitty had sometimes walked in her sleep before , but it was not really a habit with her , and the family had never thought it necessary to safeguard her . It was a still , warm night , and when she stepped out on the balcony , there was no breeze or waft of cool air to awaken her .
