Crooked House pt. 3-The Knocker-2008 IMDB 7.4/10

When the curator declines his gift of the knocker to the museum, Ben puts it on his own front door. Consequently he is woken in the night to find that he is, momentarily, in Geap Manor, witnessing Widdowson's rites. He removes the knocker and returns to the museum to find that things there are not as they had seemed before. The next day he discovers that his house is built where Geap Manor once stood and he throws the knocker in a creek. Returning home he finds that the knocker has mysteriously re-appeared on his door, placing Ben and his pregnant girlfriend at the mercy of the ghost of the childless Widdowson.
