El sótano de Oxford

In a house in an affluent neighborhood in the city of Oxford, a woman and a child are discovered by chance, locked in a basement—unidentified and barely alive. The woman does not speak, there are no records of any similar disappearances, and the elderly owner of the house claims never to have seen them before. The entire neighborhood is in shock. How could this have happened? Inspector Adam Fawley knows that, beneath an innocent exterior, many people harbor secrets. A clue emerges from one of his past cases—a disappearance he was never able to solve.
