By Martin Robinson A depressed woman who strangled her disabled husband with a cravat because he was 'too nice' only failed to murder him because a Sainsbury's driver arrived to deliver their weekly shop, a court heard. Christine Houston, 66, has admitted the attempted murder of partner Stewart, who said today she is still 'as gentle as a lamb' and he remains 'devoted' to her. Mrs Houston, who has a history of mental health problems, will be detained indefinitely in a mental hospital for her crime, but Mr Houston believes she should never have been prosecuted. Attempted murder: Christine Houston, left, was interrupted while trying to murder her husband Stewart, right,  by the arrival of a shopping delivery. Mr Houston says he loves her and she shouldn't have been prosecuted
