The rich heiress Letitia Verney has disappeared while visiting Charcombe, and Mr. Tom Lomax is suspected of abducting her. Dido is inclined to believe in his innocence, but how is she to explain by what method a young lady could enter through the front door and not appear on the other side? And this isn't the only enigma that the Elizabethan manor holds: there is a deserted wing in which lights mysteriously appear at night, a crying ghost which keeps visitors awake, and memories of old family quarrels. When the senior Mr. Lomax comes to town to defend his son, the mystery intensifies--and so does Dido's romantic life. With lives and reputations on the line, it's up to Dido to put the pieces together to save the Lomaxes and find the vanished young Miss Verney.
