In “Suspicion,” Hitchcock used the audience’s reluctance to believe Grant could play a murderer to shock them. McCann wrote, “however bleak the situation might become, they would not believe that a character played by Grant could really turn out to be a murderer. So [Hitchcock] planned to execute an audacious double-bluff, revealing Grant's character to be as bad, as cold, as evil as he had seemed to be.”
