Overview
Above Suspicion is a 1943 American spy film directed by Richard Thorpe and starring Joan Crawford and Fred MacMurray. The screenplay was adapted from the 1941 novel Above Suspicion by Scots-American writer Helen MacInnes, which is loosely based on the experiences of MacInnes and her husband Gilbert Highet.
The plot follows two newlyweds who spy on the Nazis for the British secret service during their honeymoon in Europe.
Plot
In the spring of 1939 in England, Oxford University professor Richard Myles and his new bride Frances spend their honeymoon in continental Europe. They are commissioned by the British secret service to find a scientist who has developed a countermeasure against a new Nazi secret weapon, a magnetic sea mine. Without knowing his name, what he looks like or where to find the scientist, the couple look upon the search as an adventure and cross Europe seeking clues from clandestine contacts.
In Paris, Frances is given a hat decorated with a rose as a signal for their first contact, who silently instructs them to go to a café in Montmartre. An unseen contact plants a tourist guidebook to southern Germany in Richard's coat. The couple notice a series of ink dots on a map in the book, which, linked together, form a musical staff with the opening notes to the song "My Love Is Like a Red, Red Rose." They deduce that this is their password. Three pinpricks in the same map direct them to the book's seller, A. Werner, in Salzburg. Werner instructs them to go to a certain museum, where a man named Count Hassert Seidel, calling himself a "guide," suggests that they check into a guest house run by Frau Kleist. She provides them with a book on Franz Liszt with annotations that reveal that their next stop should be the village of Pertisau in Tyrol, where they should inquire about a doctor who collects chess pieces.
