Edwin Mason was the brother of May Hardman and uncle of Christine. In January 1961, Edwin visited Christine to pay his respects to the recently dead May and gave Christine £10 to help with the bills. Christine was expecting Joe Makinson to arrive to take her to a jazz concert but Edwin answered the door to Joe and, thinking he was badgering Christine about a plumbing bill, told him to leave Christine alone.
Edwin showed up again on 12th April, when Christine was dating Joe. He had to give his approval of Joe as Joe knew that Edwin was having an affair with Hilda Wardle.
In 1963, Edwin called at Christine's lodgings while she was out and tried to get fresh with her landlady Elsie Tanner while he waited on her, but Elsie was having none of it. He came back again to harangue his niece for turning down Frank Barlow's proposal of marriage but Christine stuck to her guns, with Elsie's support.
