In the mid-1950s, the wife of Kenneth Barlow, a brilliant nurse, was found dead in their apartment in the Bradford district of England. According to Mr.

Barlow's statements, his ill wife got up in the middle of the night to take a bath before dying of illness in the bathtub. However, this death does not appear accidental in the eyes of investigators. On the bedside table, syringes. of penicillin were found. Who then killed Mrs Barlow? Her husband proclaims it loud and clear: he has no alibi!
