Uniquely structured plus 3 mysteries for the price of 1.  The central mystery halts twice and shifts twice.  The 3 mysteries ask: ghost or possession; Madeleine or Judy;  permanent or temporary mental disorders?

  The final shift occurs near the end, but is present throughout.  When the other mysteries vanish, what’s left is whether or not Scottie’s vertigo, obsessions and detachments can be cured.  But should we care?

  Scottie’s hardly the ideal boyfriend in how he treats women, and in his relationship-wake he’s not leaving many happy endings behind.  Perhaps that’s why Hitchcock ends the film with no clear statement of hope and perhaps that why Scottie is left dangling on the rooftop gutter at the start - he may be incapable of being rescued.
