The duo call upon Miss Daisy Scanlon, the young woman visited by Mr Endicott before he was injured, who was distressed but of some assistance. Returning to Baker Street, it is not long before a message from her arrives requesting a further meeting. Holmes realises at once that the appointment is a trap, but they set out to see what can be learned after ensuring that they are armed. They narrowly escape with their lives, immediately revisiting Miss Scanlon to discover that she has suffered a fatal accident in her home. Although it is not apparent, Holmes deduces that she has been murdered. It transpires that German agents have abducted a Member of Parliament, in order to gain information, and also his daughter as an incentive to gain his co-operation. Holmes knows, despite discouragement from Scotland Yard and his brother Mycroft, that these incidents also must be addressed, to prevent a blow to our country that would devastate the Empire.
