Shows like Partners in Crime

If you want that specific blend of witty domestic partnership solving mysteries together, you'd likely get the closest match with Mrs Sidhu Investigates or Shakespeare & Hathaway, both of which nail the bantering-couple-as-detectives formula with humor that actually serves the plotting rather than just decorating it. The period-mystery angle suggests Seven Dials Mystery or Rosemary & Thyme might scratch a similar itch for elegance and charm, though they trade the married-couple dynamic for friendships. If you're more flexible on the partnership structure itself, McDonald & Dodds and The Inspector Lynley Mysteries capture that mismatched-detectives sparring pretty reliably, even if the specific chemistry won't be identical.
