Synopsis:
Gang boss John Varden has eluded Batman, so the Caped Crusader increased his regular patrols of Gotham. An out of town private investigator, Thaddeus Crane, follows Batman and accidentally learns his secret identity. The media learns about Crane's discovery and publicized the detective.

Crane is soon hired for several jobs. Each time he is watched over and helped by Batman. Varden's gang captures Crane and tries to force him to reveal his secret. Crane refuses and summons Batman with a belt-radio. Varden is captured, and Batman's secret is safe because Crane is really Alfred in disguise.
