Like the other entries in the Whistler series, this one has an intriguing premise (not far removed from "Indecent Proposal") with a couple of nice twists. Unfortunately, it doesn't make for good cinema due to its static nature -- it's much more suited to the series' original medium, radio. The grungy setting of the first entry in the series (also directed by the fledgling William Castle) is sorely missed, though he does introduce a few oddball characters in passing. Nonetheless, it is worth sitting through the dull parts for the clever climax and the haunting aftermath. And there's one of those nice little walk-across-the-room bits by a sexy waitress to keep the guys alert (reminiscent of Lana Turner's rookie appearance in "They Won't Forget" or Yvette Vickers' eye-catching serveuse in "Hud"). A similar tale of a lighthouse-bound ménage-a-trois occurs in PRC's semi-noir appropriately entitled "Lighthouse".
