'The Lady of the Lake') is a 1965 Italian mystery film written and directed by Luigi Bazzoni and Franco Rossellini and starring Peter Baldwin, Virna Lisi, Pia Lindström and Philippe Leroy.

Bernard (Peter Baldwin), a well-known writer, arrives in a small Italian town near a lake to spend his winter vacation.

When Enrico's son Mario (Philippe Leroy) and his wife Adriana (Pia Lindstrom) arrive at the hotel, the two begin acting suspiciously, silently walking around the lake at night.
