They go to her room in lodgings in Notting Hill and in a slit in the lining of her father's old chest find a document which the Major recognises as being written in Swahili. The Major can understand the writing and realises that it refers to a hidden cache of expensive ivory. The Major asks if he can keep the document for the moment and will call on her tomorrow at half-past-six when he has thought of a plan of action.
