Continuity problem - Burke's car pulls up before Linda Murray's agency. He gets out, walks to the door, and rings the doorbell. Getting no answer, he opens the door. In the next shot, we see him continue through the door into the agency, but behind him, instead of the sidewalk, is an interior hallway. Later, Linda looks up from her desk in the office to see a man standing in the rain on the sidewalk next to that same door.
