Calling Paul Temple (1948 Film) Part 1 of 2.

A woman is found dead on a train, and the name "Rex" has been written on the pull-down blind. It is the third in a mysterious string of "Rex" murders, all carried out on trains. And soon there's a fourth murder. All the victims are discovered to have been the wealthy patients of a doctor who specialises in nervous disorders. The detective novelist Paul Temple and his wife Steve are called in to help Scotland Yard's Sir Graham Forbes solve the case before the serial killer strikes again.
