Harry the hit man is hired to whack Vic the victim. Vic lives in the apartment complex illustrated below, and Vic parks overnight in the circled parking spot, and always leaves for work around 8am. At 7:50am, Harry begins walking back and forth in the driveway (gray area), waiting for Vic to walk out of his apartment, or to drive past Harry. Harry repeatedly walks from point A to B to C to D to E and back to D to C to B to A. The first three times from point E, Harry sees Vic’s car parked in the circled spot. The fourth time, Vic’s car is gone, but no car drove past Harry. The driveway is the only way out. How did Vic get away?
(This easy puzzle was inspired when my neighbor drove out one morning without my seeing her)
