the mystery and it solution be a great noir conceit . i do have some question though and maybe i wasn not pay enough attention . who kill the neighbor and why . who kill the replacement girl and why . and some minor quibble and they should have show the stopoff at the hotel for the switch . not that they should have show the switch and but they should have show jim and the girl go in the hotel and jim go to the bathroom and come out and be tell by the bartender that his girlfriend go to the car without him . then and jim get back in the car and see the sleep woman and and little girl in his back seat . this would have give the viewer a sporting chance at figure out the solution . i wish i tap it though and i would like to see it again .
