A pretty ok movie, mostly notable for all the definite articles in the credits:

We’re in Russia – all the names and signs and newspapers are in Russian, then halfway through the movie they decided the setting was well established and signs start appearing in English. Captain Anton Walbrook (year after The Red Shoes) visits the card games every night but never plays because he’s determined not to lose. So he visits a creepy bookseller to learn some useful tips:

The creepy bookseller is overdoing it:

Anton learns about a terrible old woman who knows the supernatural secret to winning at games of chance (their big card game is just betting 50/50 on a single-card draw). He pretends to be interested in the pretty girl (Yvonne Mitchell of Sapphire) who works for the old lady (Edith Evans, Ghost of Christmas Past in the Albert Finney Scrooge) by plagiarizing love letters, gets close enough to threaten the old lady, who promptly drops dead, then idiot Walbrook tells the girl his whole scheme. He gets the secret of the cards from the dead woman, wins a fortune then loses it all (and the girl) the same night.
