Black and white suspense movie – probably set in England. Saw it on TV 15 years ago. In English. A man robs his own office (it could be a bank) after hours on a Friday night. He is discovered when his boss unexpectedly returns. He hits the boss over the head and escapes (don’t remember if boss is killed). He goes into the countryside and stays in a guesthouse where people read about the crime in the newspapers and someone is suspicious of him – a lot a simmering tension about whether he will be discovered.
