The Ex-Mrs. Bradford

Dr. Lawrence "Brad" Bradford (William Powell) and his ex-wife, Paula (Jean Arthur), are still in love in spite of their divorce. Paula's obsession with murder mysteries remains a wedge between them, until Brad comes across a shifty horse trainer and the suspicious death of a jockey mid-race. Paula and Brad combine to act as sleuths, bringing all the suspects together at a riotous dinner party and discovering in the process that their marriage is very much alive.
