Half an Hour (1920)

In order to help her father, Lord Dartmouth, out of financial difficulties, Lady Lillian agrees to marry the wealthy Richard Garson, whose love she does not reciprocate. After a bitter scene with Richard, Lillian consents to elope with her former suitor, Hugh Paton, leaving her jewels and a letter of explanation behind. Arriving at Paton's rooms, Lillian is told by his maid, Susie, that he is a womanizer. Just then, Dr. George Brodie arrives, carrying the body of Paton who was killed by a taxi. Lillian returns and tries to retrieve her note, but finds the drawer locked. When she appears at dinner, she finds Dr. Brodie, coincidentally invited to dinner by Richard, relating the strange story of that afternoon. Richard speculates on the woman's identity, but the doctor keeps Lillian's secret. Lillian later is able to recover her note and Richard begs her pardon for any suspicions which he had about her. Finally, realizing her husband's love, Lillian confesses all.
