John Kirk was the only companion of explorer David Livingstone to emerge untainted from the disastrous tragic expedition up the Zambezi river between 1859 & 1863. Three years later Kirk returned to Africa to the notorious island of Zanzibar ancient post of the slave trade between Africa & the Middle East. Half a century after the abolition of slavery in Britain slave trafficking persisted on Africas east coast apparently tolerated & even connived with by parts of the British Empire in the Indian Ocean. Kirk appointed as medical officer to the British Consulate in Zanzibar could do nothing. This extraordinary & controversial book brings Kirks years in Zanzibar to life. The horrors of the overland passage from the interior & the Zanzibar slave market itself are vividly described together with Kirks final bitter conflict with Livingstone who blamed Kirk for his own failings. But it was Kirks success in closing down the slave trade on the island which made him famous across the world. Using private diaries & papers a long forgotten Victorian hero & an extraordinary chapter in British history are revived in detail.
