The narrative begins in Sokoto following the death of Captain Hugh Clapperton, leaving his servant Richard Lander alone to navigate a hostile interior. Lander faces severe illness, betrayal by guides, and the constant threat of local conflicts as he attempts to secure safe passage to the coast. The text provides detailed observations of the political landscapes, including the expanding influence of the Falatahs and their wars with neighbouring states like Borghoo and Yariba.
Lander travels southward through Kano, Zaria, and Cuttup, encountering various regional kingdoms with distinct social structures and customs. His journey is marked by near-fatal episodes of thirst in the bush, treacherous river crossings, and encounters with slave caravans. Despite the persistent hostility of Arab traders who view him with suspicion, he relies on the unexpected kindness of local populations and indigenous women, who frequently offer him food and shelter.
Passing through the kingdom of Yariba, Lander is received by local monarchs, including Mansolah of Katunga, who attempts to integrate him into the royal court. He documents the elaborate fetish rituals, judicial ordeals by poison, and the widespread practice of human sacrifice observed in towns like Badagry. These descriptions offer an unvarnished look at the legal and religious frameworks governing these societies.
The final leg of the journey brings Lander to the coast of Badagry, where he faces hostility from resident Portuguese slave merchants attempting to sabotage his departure. Rescued by the arrival of a British vessel, he secures his passage back to England. The narrative concludes with the safe delivery of Clapperton's journals to the Colonial Office, bringing a definitive close to a deeply perilous expedition.
