Various Temptations

"Ronald Raikes, 31, is wanted for questioning in connection with the Victoria murders. Four London prostitutes have been strangled in a week and the known sex-offender has gone to ground. On impulse, he climbs a ladder and climbs in the open bedroom window of Clara, a plain and lonely woman who's just been reading about the slayings. Telling her not to be frightened, he finds himself pouring out a very diluted account of his life story. Despite suspecting him to be the murderer, still she shelters him, finding it all a great adventure and soon they are making arrangements for their wedding. To celebrate his 32nd birthday, Clara throws him a party and, much to her own amazement, dolls herself up for the occasion, getting her hair done, buying a new blouse and even applying a dash of lipstick which is probably not the most advisable course of action in the circumstances, though the creepy undercurrent suggests she had a death wish all along." -- Vault of Evil
