The second story about the Jillies is a fairly routine kidnapping story, made interesting by the setting, which is the dock land area of London (now changed out of all recognition). Anyone visiting. Dock land now will search in vain for the boats, the sailors, and the dockers who throng the pages of this book. The Jillies are hampered by having to do their investigating in the thick and stifling London fog, which slows them down somewhat. But of course they triumph in the end, who could doubt it?
