Civil War treasure is hidden in the house apparently, though Drummond promises to long suffering Phyllis that they will get married first. However when the Professor is found dead all plans go to pot...
A classic country house film complete with hidden passages, mysterious goings on, the unknown identity of a killer and even medieval torture equipment! Tenny (E.E. Clive), Algie (Reginald Denny) and the Colonel (H.B. Warner) are on hand as usual. Drummond and Phyllis still did not manage to get married, better luck next time!
