Bulldog Drummond at Bay plot
"All New! All Thrilling!"
'Bulldog' Drummond is on holiday at his mansion in England, when his house is ransacked by two thieves. After they leave, he finds a map with some mysterious letters written on it. Doris Meredith comes over the next day and pretends to have car trouble. Drummond knows better but plays along with her. Drummond calls Scotland Yard Inspector Holmes and is told that some of the letters are part of a code name for a man who disappeared while carrying some diamonds from France to England. Doris tells Drummond that the man is her brother.
