The Still Alarm (1918)

"Bird," a clerk in Fordham's drugstore, agrees to place a large sum of money in the store's safe for a traveler, but when the man requests a bottle of medicine, Bird poisons the remedy, and the visitor is found dead in his hotel. Bird flees with the money, but several years later he returns, the money long since squandered. Unless Fordham's daughter Eleanor marries him, he threatens, he will tell the police that Fordham committed the crime.
