The Key To Stirling Manor

"She leaned back, shielding herself with the lace curtain, but it was as if the girl could see right through it. She smiled widely and waved, then went into the shed. Renee froze. The girl had gone into the shed, but she hadn't opened the door first!"
When Renee is sent to spend the summer holidays with her Great Aunt Bella at Stirling Manor, she learns very quickly that it is no ordinary house. Things that move by themselves, music that drifts from an ancient piano, and glimpses of a phantom girl about her own age all leave Renee curiously excited.
But all is not well at Stirling Manor. Aunt Hannah, part owner of the house, is trying to force Aunt Bella to sell. Renee realizes that if the house is sold, it is very probable she will never see the ghostly girl again.
