The Open Door and the Portrait. Stories of the Seen and the Unseen.

Oliphant was known for her exploration of themes related to the supernatural and the mysterious in various short stories and novels. If The Open Door and the Portrait is indeed another collection of her stories exploring similar themes it might contain narratives that delve into the mystical occult or unseen forces that impact human lives. For specific details about this particular book or collection I'd recommend checking library catalogs online book retailers or databases that specialize in literary works for more accurate and detailed information on its publication contents and availability.
