In Kimberley, young detective Trim sets out to catch the elusive criminal Jemmy Miller, only to learn that the case reaches back to a darker scandal: a brutal strangler named Mulvey, an ex-convict believed to have vanished into the African interior and found sanctuary among the Narugas. Warned that this hidden refuge has become a haven for desperate men, Trim refuses to wait while justice fails and prepares an expedition into dangerous country with his steadfast companion Dobbin. What follows is a hard-riding African adventure of nerve, diplomacy, and peril. Trim crosses frontier lands, bargains with suspicious elders, and stares down Massai warriors with nothing but confidence, gifts, and quick thinking. By river and raft, through rapids and rough camps, he pushes deeper toward Naruga territory, even rescuing a drowning donkey along the way. But the journey grows sinister when he discovers the Bangwas under Naruga control and witnesses a savage execution in the dark: a bound prisoner hoisted into a tree and killed before a chanting crowd. Caught spying, Trim boldly confronts the king, only to find himself drawn into a tense interview in a crude hut, where the ruler fears English retaliation and Trim must decide how much to reveal.
