|'The Yellow Needle'
by Patrick Campbell
Sir Wilberforce Lungi arrives in London in order to negotiate independence for his African nation. But when an attempt is made on the delegate’s life, Steed is called in to investigate. After Steed travels to Africa, he discovers that Jacquetta Brown, Sir Wilberforce’s assistant, is a member of an opposing group, but he is then captured. Steed escapes, and manages to warn Doctor Keel, who is an old friend of Lungi. An attempt by Jacquetta to replace Lungi's insulin with lethal yellow fever virus is thwarted by Keel, when he arrives in time to overpower her.
