If

A standard issue late 19th century British middle class family man receives a gem from a Persian beggar that allows him to go back in time. Despite protests from his wife he uses it to return to a time when he suffered a minor slight from a railroad attendant, thinking his life would proceed quite the same as it did the first time once this slight is corrected. Of course, he ends up in Persia, worshipped by the locals, being plotted against by a blood-thirsty woman who cannot seem to decide whether she would rather marry him or have him killed.
