When financial problems force her family to sell their London home, a strange solicitor arrives with an astounding offer: the use of a distant manor house abandoned for eighteen years. The Fosters journey to imposing Pembrooke Park and are startled to find it entombed as it was abruptly left: tea cups encrusted with dry tea, moth-eaten clothes in wardrobes, a doll's house left mid-play . . . The handsome local curate welcomes them, but though he and his family seem to know something about the manor's past, the only information they offer Abigail is a warning: Beware trespassers who may be drawn by rumors that Pembrooke contains a secret room filled with treasure. Hoping to improve her family's financial situation, Abigail surreptitiously searches for the hidden room, but the arrival of anonymous letters addressed to her, with clues about the room and the past, bring discoveries even more startling. As secrets come to light, will Abigail find the treasure and love she seeks...or very real danger?
