A valuable wedding present, the famous Rigby bowl, is discovered to be missing from the Considine home. Suspicion falls upon Penny, the scullerymaid, who has been seen kneeling beside the locked drawing-room door. Queenie, another maid, is sent upstairs, to search Penny's trunk and returns with a large parcel all wrapped up ready for taking away. This is presumed to be the lost present. Then the bowl is found elsewhere, and on investigaiton the wrapped-up parcel proves to be a large flower-pot, which Penny had intended as a wedding present for Nancy, the bride. Penny says she had been looking through the keyhole of the drawing-room door to get a glimpse of the presents.
